The Kidde 1500-1 is a 1-1/2" fixed rod catch plate extension for Kidde electromagnetic fire door holders. When the door holder mounts at a different depth than the door surface, this extension bridges the gap so the armature plate contacts the magnet flush - keeping holding force at full rated capacity.
Built for the fire door installer
Chrome-plated steel construction handles the daily impact of commercial fire doors without corroding or bending. The fixed 1-1/2" length fits standard recess depths where the door sits proud of the holder mounting surface. Threads into the catch plate assembly on Kidde electromagnetic door holders (1500 series accessories). UL and ULC listed as part of the Kidde electromagnetic door holder system.
Why it matters on the job
- Maintains full holding force: flush armature-to-magnet contact prevents partial engagement and nuisance releases
- Chrome-plated steel: resists corrosion in high-traffic commercial environments
- Fixed 1-1/2" length: no adjustment needed when the recess depth is known at rough-in
- Drop-in compatibility: threads directly into Kidde electromagnetic door holder catch plate assemblies

What does the 1500-1 catch plate extension do?
Extends the catch plate assembly by 1-1/2" so the armature contacts the electromagnet flush. Without it, partial engagement reduces holding force and risks nuisance door releases.
