Installation & Operation

1. Review manufacturer specifications and verify door preparation requirements including door thickness, stile width compatibility for ultra-narrow applications, and proper alignment between door and jamb.
2. Use manufacturer-provided templates to mark mounting hole locations accurately on the sliding door stile, ensuring adequate clearance for the compact 1/2" x 3-3/16" x 1-1/8" case dimensions.
3. Prepare the door stile by drilling required holes and routing as specified in manufacturer instructions, taking care to maintain structural integrity of the narrow stile.
4. Install the deadlock case and secure with provided mounting screws per manufacturer torque specifications, selecting appropriate hub slot position based on available turn clearance.
5. Adjust bolt projection using the exposed adjustment screw to achieve proper alignment with jamb strike, utilizing the full 3/16" adjustment range as needed to compensate for misalignment.
6. Test deadlock operation to verify proper bolt extension, retraction, and self-protecting function. Install cylinder pull separately if keyed operation is required. Refer to manufacturer documentation for complete installation details and troubleshooting.
