Is your front door truly secure? Beyond the lock, small door hardware like a door chain (security chain) and peephole can make a real difference. As a trusted door hardware brand, YALIS helps you choose wisely.
1. What Security Door Hardware Exists?
Door chain (security chain) – lets you open the door slightly while keeping it secured.
Peephole (optical viewer) – see outside without opening the door.
Anti-peephole opener cover – prevents tool-based unlocking through the peephole.
C-grade lock cylinder – resists picking & bumping.
Heavy strike plate + long screws – stops kick-ins.
Hinge bolt – prevents door removal.
2. Is It Really Worth It?
| Hardware | Worth? | Why |
| Door chain | ✅ Yes | Cheap protection when talking to strangers (delivery, sales). |
| Optical peephole | ✅ Yes | Standard need. Choose anti-peephole type. |
| Anti-peephole cover | ✅ Must | Under $5 – blocks a real break-in method. |
| C-grade cylinder | ✅ Must | Best value upgrade. |
| Heavy strike plate | ✅ Must | With long screws, stops kicks. |
3. Which Doors Need These?
Yes, install:
Front entry door → chain + peephole + C-grade core + strike plate
Garage-to-house door → same
Rental apartment door → chain + peephole (tenant safety)
No need:
Bedroom / bathroom doors → privacy handles only
Closet doors → no security hardware needed
4. Correct Installation Tips
Door chain: Mount the chain base on the door frame (not the door). Use 5cm+ screws into the wall stud. Keep chain short (door opens only 10-15cm).
Peephole: Choose anti-peephole and anti-removal types. YALIS peepholes lock from inside – can’t be unscrewed from outside.
Anti-peephole cover: Fits over your door handle’s interior turnpiece. Simple to install.

6. FAQ
Q1: Can a door chain really stop an intruder?
A: Not fully, but it prevents “push-in” attacks. It buys you time to close the door and call for help.
Q2: Can a peephole be a security risk?
A: Yes – standard ones can be removed or reversed. Choose an anti-peephole and anti-removal model like YALIS offers.
Q3: Do I need an anti-peephole cover?
A: Absolutely. It costs very little and blocks the “peephole opener” burglary tool.
Q4: I rent an apartment. Can I install these?
A: Yes – use a stick-on door chain (no drilling) and a non-damage peephole. Keep the original parts to restore later.
Q5: Which doors don’t need a door chain or peephole?
A: Indoor doors (bedrooms, bathrooms, closets) have no security requirement.
