The 8800 Interlocking / Starwheel and the new P8800 Pullman Rim Exits require different door preps.
- However, if a P8800 is retrofitted over a previously installed 8800 Starwheel, the holes from the Starwheel install will no longer be visible.
The new P8800 has different cylinder/trim prep, different mounting prep, different strike prep compared to 8800 device.
The P8800 strike can cover the 8800 strike prep holes when retrofitted
