90-Degree Trigger-Release Self-Locking Folding Hinge (Yellow Zinc)

Product Overview

Our 90-Degree Trigger-Release Self-Locking Folding Hinge is the ultimate structural component for collapsible workbenches, heavy-duty extension shelves, and folding bed bases. Finished in a classic yellow zinc plating for superior corrosion protection, this hinge utilizes a high-tension spring and a physical trigger-latch to lock securely at 90 degrees, providing a massive load-bearing capacity for industrial and commercial use.
