Square framed Catch Covers are most often used to retrofit fish houses with homemade hole covers already in the floor. 12" hole opening. The rough floor cut-out is 12-3/4" x 12-3/4". The flange is 1-7/8" tall. The top dimension is 16" x 16".
Like the Original Round Catch Covers, the Square Catch Covers are injection molded from the proper blend of cold weather materials making them practically indestructible on the ice. The lid snaps into place and won't pop out over the roughest roads, keeping snow and road salt out of your house and all your gear inside the house!
Secure Catch Cover rings to the floor using #10 3/4" stainless steel screws. Do not to over-tighten the screws.
