The Kidde 250-COPLT adapter plate bridges the mounting footprint between the legacy 240-COE carbon monoxide detector and the current 260-CO replacement. Drop the plate over the old backplate screw holes, mount the 260-CO on top, and skip the drywall patching. Ships as a 5-pack to cover multi-unit retrofit jobs in one order.
Built for the retrofit installer
When a building-wide CO detector swap moves from the 240-COE to the 260-CO, the new detector's mounting pattern doesn't match the old one. This plate covers the gap - literally. It sits flush over the existing cutout, gives the 260-CO a clean mounting surface, and keeps the finished look intact without paint touch-ups or wall repair.
Why it matters on the job
- Covers the old footprint: hides screw holes and wall marks left by the 240-COE removal
- Clean finished appearance: flush-mount plate keeps the installation looking professional
- 5-pack packaging: one order handles multi-unit hallways, floors, or common areas
- No wall repair needed: eliminates drywall patching, sanding, and repainting between detector swaps

What is this plate for?
The 250-COPLT adapter plate covers the mounting footprint left behind when you remove a Kidde 240-COE CO detector. It provides a clean mounting surface for the replacement 260-CO detector without wall repair.
Does this work with CO detectors other than the 240-COE and 260-CO?
No. This plate is specifically designed to bridge the mounting pattern difference between the Kidde 240-COE (being replaced) and the Kidde 260-CO (the replacement). It is not a universal adapter.
How many plates come in the package?
Five. The 5PKG suffix in the SKU indicates a 5-pack, sized for multi-unit retrofit projects.
Do I need any special tools to install this plate?
No special tools. The plate mounts over the existing backplate location using standard screws. The 260-CO then mounts to the plate per its normal installation instructions.
