Details: Legacy Manufacturing 1559SS Cam Lift Mortised Hinge, Finish-Stainless Steel

Designed for sound-rated and other heavy doors up to 900 pounds. Manufactured from high precision stainless steel casting, the cam lift hinge provides a smooth 1/2 inch drop over a rotation of 180 degrees for superior sealing performance. Available for right or left-hand swinging doors. Sold in pairs.

The mortise cam lift hinge is a high precession investment stainless steel casting. It is designed to move the door upwards while swinging the door open and in reverse, it will bring the door down when closing it. The cam function of the hinge is to prevent the door from contacting the frame while opening. Cam lift hinges will not bind door closures when doors are hung within accepted industry standards.

This specially-designed movement of the hinge, lifting and lowering the door with the swing helps the door achieving higher STC rating. This occurs due to greater contact with the acoustical gasketing, making a better and tighter door seal.
