MAXTECH Jimmy Proof Automatic Deadlocking Slam Lock Satin Chrome US26D

Solid Jimmy Proof Slam Lock

This solid Jimmy Proof automatic deadlocking slam lock is designed for residential or light-commercial doors that require automatic relocking on every closing. The single-cylinder set uses an SC1 keyway and is keyed different so each unit operates on its own key. A satin chrome US26D finish provides a clean, modern appearance that suits a variety of door styles.

Hold-back and shutter guard features

A hold-back function lets the user keep the door unlocked or disable exterior key operation when convenient access is needed. The shutter guard prevents tampering with the lock mechanism even if the outer cylinder is attacked. Flat strike and solid brass construction contribute to reliable daily operation without electronic components or batteries.

Automatic deadlocking under attack

The Jimmy Proof concept resists frame-spreading attacks and automatically deadlocks the bolt when the door slams shut. This behaviour remains consistent during repeated forced-entry attempts because the locking action is mechanical rather than spring-dependent. The solid bronze alloy body maintains structural integrity where thinner stamped locks might deform under sustained prying force.
