Medium Duty Aluminum Incremental Locking Hinges

Adjustable Locking Hinges provide positive locking at any 10° increment. Once locked, the hinge becomes an absolutely rigid joint, able to withstand 500 inch-lbs of torque (5:1 safety factor). Applications include adjustable fixtures, rotating fixtures, welding fixtures, trunnion mounting, adjustable handles, foldable handles, adjustable part trays, adjustable shelves, adjustable racks, adjustable and/or fold-away work surfaces, positive positioning of lighting or nozzles, and collapsible structures.

INLINE MODEL:

Hinge extensions line up in the same plane. Total range of movement is 220° — see Dimensions page for part numbers.

OFFSET MODEL:

Hinge extensions are offset to allow full 360° rotation. Offset hinges should usually be used in pairs, to avoid off-center loading on a single hinge and ensure full strength.

Push Button versus Cable Release: 

Both the 220 degree Inline and the 360 degree offset come in both a Push Button and a Cable Release option. The cable release option also has a functioning push button but allows for a cable to be attached through a hole in the mechaisms to release and adjust the rotation.
