Question:

I have an Atwood 311011 combo detector that needs replacing. Measurements 3-9/16” long x 3-7/16 wide. Is there a combo carbon monoxide/LP detector that will fit the existing cutout ?

I recommend the RV Propane Gas and Carbon Monoxide Detector, # RS54FR that has 2 universal mounting brackets included. The alarm dimensions are 4-1/4" long x 2-5/8" wide x 1/2" thick.

There are two included mounting brackets to choose from, dimensions are 7-1/4" long x 3-3/8" wide or for the smaller bracket, 5-3/4" long x 4-1/4" wide. Select the option that best fits your need for location of installation.
