The Atwood RV Carbon Monoxide and Propane Gas Detector part # AT36681 will be an excellent replacement for the ProTECHtor LP Gas Detector. This is going to be the closest option that we currently offer to the Protechtor's size. It requires a 3-9/16" long x 3-7/16" wide x 1" deep cutout hole and has a 3-wire installation. This detector has a 7 year lifespan, which is pretty standard, and will alert you when it's time for replacement. view full answer...
It sounds like you're looking for a replacement grab handle like the:
-Lend-a-Hand Folding Grab Handle for RVs - Black with Black Foam Grip # AM-800.
This grab handle measures 24" tall, 14" wide, and is black in color, however if you're able to let me know what size handle you're needing replaced I'd be happy to find you a correct replacement. view full answer...
