6 Best Door Chain Picks for Apartment Security
Fitoon Door Chain Lock, 2-Pack is the top pick for most buyers because it gives you two matching locks in one purchase. For shoppers seeking the best door chain, that simple two-pack value makes this Fitoon option a practical starting point.
This guide is for renters, homeowners, and anyone who wants added door security without replacing the main lock. For this type of hardware, check the chain length, metal construction, screw quality, and whether the mounting plates fit your door and frame. A compact design may suit a narrow entry, while a longer chain can allow more opening space, but extra reach can reduce control. The six picks below are ranked with clear reasons and honest drawbacks for each, so you can match the lock to your door and budget.

6 Door Chain Picks Worth Considering
The list is ranked by security, build quality, and ease of installation, counting down to the top pick.
6. Prime-Line U 9852 Chain Door Guard
Best for: Basic entry-door viewing and ventilation
The Prime-Line U 9852 is a chain door guard for swing-in entry doors. Its stamped-steel mounting plate and welded steel chain use a white painted finish across the assembly. The base plate measures 3-5/16 inches wide by 1-3/8 inches tall, so it takes up modest space on the door and frame. This single pack includes the mounting hardware needed for installation.
The main benefit is controlled opening. You can keep the door partly closed while checking who is outside or allowing limited airflow. The chain measures 6 inches long and has eight welded links, giving the guard a defined opening range rather than a fully open door. Its white finish should blend with many light-colored doors, while the steel construction offers a sturdier option than plastic guards. Installation should place the guard above a child’s reach, especially in homes where children could access stairs, exterior steps, or other unsafe areas. At $5.36, it fits simple door-safety upgrades, but it is not a replacement for a deadbolt or stronger security hardware.
Pros
- Six-inch, eight-link welded steel chain limits how far the door can open.
- Steel plate and chain provide more structure than an all-plastic guard.
- White finish and compact 3-5/16-by-1-3/8-inch plate suit many entry doors.
Cons
- It works only with swing-in doors, so outward-opening doors need another solution.
- A short chain allows viewing and ventilation, but it does not provide full door security by itself.
5. Fitoon Door Chain Lock, 2 Pack
Best for: Child-safe entryway checks
The Fitoon two-pack adds a secondary barrier to interior doors. Each lock uses a stainless steel chain with eight welded links, a 3.4-inch lock plate, and a 7.35-inch chain. The door can open slightly for viewing or airflow, while the chain limits how far it moves. Installed high on the door, it can help keep children from opening certain rooms without supervision. It may also stop pets from pushing doors open or slipping through small gaps.
Installation requires marking the positions, drilling holes, and securing the hardware with the included 12 extended screws. The plates can sit above or beside the door frame, and the set is listed for homes, bedrooms, apartments, and hotel rooms. At $5.29 for two locks, it offers an inexpensive way to add basic privacy and entry control. Still, buyers should compare the listed measurements with their door and frame before ordering. The compact size may not suit every trim style or door layout.
Pros
- Two locks cost $5.29, making this a low-cost option for multiple doors.
- A 7.35-inch chain allows limited opening for viewing or ventilation.
- High installation can reduce access for young children and small pets.
Cons
- Installation requires drilling, accurate measuring, and a suitable door frame.
- A chain lock is a secondary barrier, not a replacement for a deadbolt or primary security lock.
4. Kryvlexa Door Chain Lock
Best for: Apartment residents wanting controlled entry
The Kryvlexa Door Chain Lock adds a basic check-before-opening step to a residential door. It uses 304 stainless steel and a reinforced metal structure for regular household use. The 7.08-inch chain lets you open the door partway while keeping it attached to the latch. That can help when checking a visitor or receiving a delivery. At $9.99, it offers a low-cost option for bedrooms, apartments, and front doors.
The set includes one chain lock and mounting screws. Its 4.08-inch latch plate and 4.02-inch mounting-hole distance matter when checking compatibility with an existing door and frame. The compact black and silver finish options can suit different hardware styles, although the listed product name identifies the finish as silver. An adhesive mounting method may work on some smooth surfaces, but adhesive is not listed as included. Use the screws when the door material allows a more secure attachment. This hardware controls how far the door opens, but it should not replace a primary lock.
Pros
- 304 stainless steel construction suits repeated indoor residential use.
- The 7.08-inch chain allows partial opening for visitor checks.
- Mounting screws are included with the single chain-lock set.
Cons
- Buyers must verify the 4.08-inch plate and 4.02-inch hole spacing before ordering.
- It adds a secondary door check, but does not replace a deadbolt or main entry lock.
3. INBOF Door Chain Lock, 2-Pack
Best for: Renters needing basic door control
The INBOF 2 Pack Door Chain Lock adds a secondary barrier to an inward-opening door. Each set includes a chain-and-plate assembly made from stainless steel, plus six screws, for 12 screws across the two-pack. The chain lets you open the door a small amount before releasing it fully, which can help with quick visual checks, airflow, or controlled access.
The thickened chain and plates should suit common entry doors, bedroom doors, dorm rooms, rental spaces, cabinets, and some windows. Stainless steel resists rust and everyday wear better than plain steel, while polished edges reduce rough contact during use. The included screws are described as longer and thicker, but the listing does not provide their exact length, plate dimensions, or chain length. That missing sizing information matters. Check the product images and measure your available mounting area before buying. These locks can also limit access for children or pets, though they should not replace a primary deadbolt or a properly secured door.
Pros
- Two locks cover two doors or provide a spare.
- Stainless steel construction resists rust and routine wear.
- A partly opened door allows limited viewing and airflow.
Cons
- Exact chain length, plate size, and screw dimensions are not listed.
- A chain lock is a secondary barrier, not a substitute for a deadbolt or high-security lock.
2. Solid Brass Door Security Chain Guard
Best for: Homeowners wanting a secondary door lock
This door chain guard adds a second layer of control when opening an entry door. It uses solid brass for the guard and chain, a material that resists rust better than untreated steel. The chain is described as thicker, longer, and larger than many standard options, which may provide more reach and resistance than a lightweight chain lock. At $9.99, it offers a low-cost upgrade for a front, back, or apartment door.
The package includes mounting hardware, so buyers do not need to source separate screws or fittings. Installation still requires marking the door and frame, then securing the plates firmly. The chain lets you open the door slightly while keeping a physical limit on how far it moves. That can help with deliveries or unfamiliar visitors, but it should work alongside a quality deadbolt, not replace one. Siwil Direct provides a 1-year backup period. Product dimensions are not listed, so check the chain length and plate size before ordering, especially for narrow frames or unusually thick doors.
Pros
- Solid brass construction offers durable, rust-resistant hardware.
- Longer, thicker chain design may provide more strength and reach.
- Mounting kit is included for a simpler installation.
Cons
- It is a secondary lock, not a substitute for a deadbolt or reinforced strike plate.
- Missing dimensions make fit harder to confirm before purchase.
1. Fitoon Door Chain Lock, 2-Pack
Best for: Child-safe apartment entry doors
The Fitoon 2 Pack Door Chain Lock adds a simple secondary barrier to an interior door. Each set includes a 3.4-inch lock, a 7.35-inch chain, and 12 screws. The chain uses eight welded steel links with gong wire, while the black finish suits most basic door hardware. At $5.99 for two, it offers a low-cost option for bedrooms, apartments, hotels, and home entry doors.
Its main benefit is controlled opening. You can open the door a few inches to view visitors, allow some ventilation, or keep children and pets from pushing the door fully open. The lock can sit above or beside the frame, depending on the door layout. Installation requires measuring, marking, and drilling, so the process may take only a few minutes if the needed tools are ready. Check the listed dimensions before ordering, since the chain length limits how far the door can open.
Pros
- Two locks cost $5.99, useful for covering separate doors.
- The 7.35-inch chain permits limited viewing and airflow.
- Includes 12 screws for a complete basic installation.
Cons
- Installation requires drilling into the door or frame, which may not suit renters.
- This is a secondary door restraint, not a replacement for a deadbolt or stronger entry lock.
Buying Guide
The most important factor is mounting strength, because a chain is only as secure as the screws and door frame holding it. Choose a model with a reinforced strike plate and hardware suited to your door material.
- Mounting hardware: Look for steel plates with at least four screw holes. Screws should measure 1 inch or longer for solid wood, while metal frames may require compatible anchors.
- Chain length: An 8- to 12-inch chain fits many entry doors. Measure the gap between the door and frame before buying, since excess slack reduces control.
- Material and finish: Choose a steel chain and metal plates. Zinc-plated or stainless finishes resist rust better than unfinished steel, especially near covered outdoor entrances.
- Door compatibility: Confirm that the set fits inward-swinging doors and your door thickness, often 1⅜ to 1¾ inches. Check clearance around molding, locks, and storm doors.
- Release mechanism: Pick a smooth slide or release tab that works with one hand. The chain should let you open the door only a few inches, usually 2 to 4 inches, before full release.
If you cannot have everything, prioritize a strong mounting plate and correctly sized screws over finish or appearance.
Frequently Asked Questions
How does a door chain work?
A door chain lets you open an entry door slightly while keeping the chain attached to the frame and door. It adds a basic check before you admit someone, but it is not a substitute for a deadbolt or reinforced strike plate. Look for a metal chain, solid screws, and a sliding track rated for your door material.
What makes a door chain secure?
A good door chain has a thick metal link chain, a secure door plate, and a frame mount with screws long enough for the material. Choose a model with a chain length around 6 to 12 inches, depending on how far you want the door to open. Avoid mounts that attach only to thin trim.
Can door security chains stop forced entry?
No, door security chains cannot reliably stop a determined forced entry because the chain, screws, or door frame can fail under heavy impact. They work best as a short-range opening limiter for identity checks. For stronger protection, pair one with a deadbolt, a reinforced strike plate, and 3-inch screws installed into wall framing.
Are door chains suitable for apartment doors?
Door chains are suitable for many apartment and house entry doors, but only when the door and frame provide a solid mounting surface. Renters should check lease rules before drilling, since installation commonly requires four to six screws. A slide-bolt or removable security bar may work better when permanent changes are not allowed.
Conclusion
The Fitoon Door Chain Lock, 2-Pack, is the top pick for renters and households that want two basic entry doors covered without paying for a large kit. If your priority is maximum resistance rather than value, choose a reinforced steel chain model with longer screws and a sturdier strike plate instead, because those parts can provide a more secure installation on compatible wood doors. Before buying, double-check the chain and plate sizes, compatibility with your door frame and trim, the number of locks in the package, and the current price. A chain lock adds a useful warning barrier, but it should not replace a securely locked door or a peephole.
