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.
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.
Mounting: The version shown here has one mounting flange and one round hinge extension. 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 round hinge extension fits 3/4" ID pipe or tubing. The tapped 1/4-20 mounting holes can also be used to attach a plate or angle bracket.
