A hidden fastener used to attach pickets to rails for a clean look. Simply route or drill a 3/8" hole in the picket, and a matching hole in the rail, and snap this clip into the picket, then snap the picket to the rail. No glue, no screws, no rivets, no caps.
Used instead of notching for assembly and repair of rail to post connections. Angled points extend through holes at end of rail, with "U" shaped bend inserted into rail. Slide rail into routed hole in post. Angled points compress as the rail slides in, and once past the wall of the post, rebound to lock the rail in place.
