How to Check Your Size
First determine whether your deck plate is screw-out or pry-out. Screw-out covers have a threaded lid that twists open, while pry-out covers snap into the frame.
Then measure the clear opening or hole cutout, rather than relying on the overall outside diameter of the flange. The outside flange is considerably larger than the nominal deck plate size.
If available, also check the underside of the lid or frame for a Beckson model or size marking before ordering.
