The Rail Stair Double Connector design allows fitting to go through intermediate posts on ramps or stairs, placing the fulcrum into the center of the post and allowing adjustment to 45 degrees up or down. The set includes two ends, connecting bar and center bolt. The fitting requires special slot and rivet nut in the post (supplied with complete systems).
The tube is placed over the end for a seamless fit. Rail adhesive (supplied with complete systems) is required to bond with tubing.
