Sea-Dog 1 Inch Concave Base Deck Hinge with Removable Pin, 316 Stainless Steel Rail Mount Fitting - 270245-1

The Sea-Dog 270245-1 is a 1 inch concave base deck hinge with a removable pin, built to mount an eye end for Bimini top applications. The concave base is shaped to rail mount on 1 inch tubing, giving a secure, flush fit against curved rail surfaces. Unlike a fixed-pin hinge, this version uses a spring loaded quick release pin so the top can be removed and reattached in seconds without tools, which is useful for storage, trailering, or quick access to the boat.

The hinge is constructed of investment cast 316 stainless steel, chosen for its corrosion resistance in saltwater and marine environments. The base measures 3/4 inch by 2-1/4 inch and uses a 1/4 inch diameter pin. It installs with two #10 flat head fasteners, which are not included, so the mounting hardware should be sourced separately based on the mounting surface. This hinge is part of Sea-Dog's Side Mount Hinge Fittings line used across Bimini top and canvas hardware applications.
