DISEC DN28PST-AN – Anti-Pull Cylinder Protection Plate for Garage Door Locks
The DISEC DN28PST-AN is a hardened steel anti-pull cylinder protection plate for locks installed on up-and-over garage doors. Its overall dimensions are 170 × 60 mm, with 39 × 139 mm fixing centres and 70 mm handle-to-cylinder centres.
Additional cylinder protection
The DN28PST-AN reinforces the external lock area, helping resist attempts to break or pull out the cylinder. It provides supplementary protection for compatible garage door locking systems.
The plate is intended for installations where the cylinder projects 7–12 mm from the mounting surface.

Compatibility and installation
The DN28PST-AN is intended for compatible up-and-over garage door locks, including selected PREFER, FASEM and ISEO configurations.
Before installation, verify the 70 mm handle-to-cylinder centres, 39 × 139 mm fixing-hole arrangement, cylinder geometry and 7–12 mm projection. Compatibility depends on the actual lock dimensions, not the brand alone.
The protection plate does not include the lock or cylinder.
Before ordering: compare the official DISEC dimensioned drawing with the existing lock. Pay particular attention to the 70 mm handle-to-cylinder centres, which distinguish the DN28PST-AN from the 67 mm DN22PST version. Contact Matteoda for technical assistance and estimated delivery times.
