#1400 Universal Door Lock Release Flag Installation Guide 
Designed to attach to different interlocks so the same release tool can be
used. Mounting on the connecting rod is also the same for locks with
similar assemblies. Tri-lok’s versatility is especially helpful where different
interlocks are used in the same building complex or on campuses.

  as the present hole about 3" long.

   rod. This will provide a guide for drilling out 7/8" holes.

   Be sure wide slot in rear of receiver is perpendicular to floor.

- in hole on inside of door. Engage threads of retainer with threads 
- of receiver and hand tighten.

- obtained and receiver face is flat against outside face of door.
