The ST-97S stainless steel center pivot cabinet hinge is employed when a minimum of visible hardware is desired or when the door must swing free of its frame. It is mortised into the top and bottom of the door and frame; only the pivot is visible. Stainless steel gives the hinge a modern look and does not tarnish, making it suitable for kitchen, bathroom, and marine applications. The leaf measures 3-1/4" x 3/4" x 5/16". The hinge is sold in pairs and installation instructions are available.
