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. Patent numbers 5,586,363 and 5,689,999. Other patents pending. Made in USA.

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. Make sure that rotating loads are balanced — see Dimensions page for part numbers.

The version shown here has two mounting flanges. The flange provides two options for mounting: 1) two 1/4-20 tapped holes allow fastening an object to the mounting flange; 2) two 9/32"-dia clearance holes for 1/4" or M6 screws allow fastening the mounting flange to a surface. The tapped 1/4-20 mounting holes can also be used to attach a plate or angle bracket.

Avoid any possible pinch points, especially with heavy loads. Do not release the hinge unless adequate support for the load is in place. Do not let loads swing freely. When using offset hinges that can rotate 360°, always ensure that loads are balanced in the rotational axis.
