20x20 T-slot latch

This is a small latch designed for 20x20mm T-slot such as OpenBeam. It is specifically sized for use when latching a door closed using the hinges available at FramingTech: http://www.framingtech.com/c3/c65/c66/c94/20mm-x-20mm-fixed-hinge-p270.html

It is designed to be mounted with, and to mate to, standard M5x6mm low-profile socket head cap screws but should work unmodified with pretty much any M5x6 screw.
