Guard Security 1404B Double Cylinder

The Guard Security 1404B is a brass jimmy-proof deadlock designed for residential or light commercial doors. Its double-cylinder mechanism requires a key on both sides, preventing intruders from unlocking the door after breaking adjacent glass. The SE1 keyway and five-pin rekeyable cylinder suit owners who want control over key duplication.

Surface-Mount Installation With Angle Strike

This lockset mounts on the interior surface of the door, avoiding deep mortise cuts and suiting door thicknesses from 1-3/8" to 2-1/2". The included angle strike aligns with the frame jamb so the vertical bolt engages fully, locking the door to the jamb rather than just the strike plate. Die-cast housing supports the mechanism without needing a reinforced door core.

Vertical Bolt Resists Sustained Prying Force

Under sustained attack the vertical bolt distributes prying or kicking loads across the door-to-jamb connection instead of concentrating force on a single latch point. The brass rim cylinder maintains tumbler alignment during prolonged manipulation attempts, while the die-cast housing resists deformation that could otherwise create a gap for tool insertion.

Questions about this item

How far can the bolt travel before it hits the strike on a 2-1/2" door?

The lock fits doors from 1-3/8" to 2-1/2" thick, so the bolt throw is designed to engage the angle strike across that full range.

Does the die-cast housing run hot or make noise after hours of locking and unlocking?

The housing is passive die-cast metal with no motor or electronics, so it generates no heat and makes no sound during normal operation.

Will my existing SE1 keys work with the 5-pin cylinder, or do I need new ones cut?

The cylinder uses the SE1 keyway and comes with two keys; any key cut to the SE1 profile and matching the 5-pin depths will operate it.
