This is an expansion-type right-angle connector, assembled with two structural parts, screws and nuts. One end inserts into the lean tube, while the other clamps onto the outer protruding groove of the lean tube. It secures two lean tubes at a 90° angle via fasteners.

Matched with standard hex screws, it enables easy 90° right-angle connection without specialized tools, and allows convenient modification and adjustment later on.

As a fitting for aluminum alloy lean tubes, it is widely used in lean tube frame equipment such as turnover carts and workbenches.
