• Hex-head bolt threads easily into a spring nut, connecting fitting to channel in one quick one-hand operation.

• Chamfer in the nut eases starting of the bolt. Nut teeth create a strong, vise-like grip when tightened against the inturned channel edges.
• Channel edges and the nut's tapered grooves act as guides to provide fool-proof alignment of connection.
• Nut teeth create a vise-like grip, tying sides together in a strong “box” configuration, when the nut is tightened against the in-turned edges.
• Spring allows precision placement anywhere along channel length, then holds the nut in position while connection is completed.
