Clip T 

The Clip T is designed to snap onto 1 inch PVC pipe while either a 1/2 inch PVC support pipe is inserted into the perpendicular socket, or a 1 inch pipe is fitted to the outside of the socket. Perfect for support legs and other structural supports. Also useful for holding up fruit tree branches.
Note: attaching the 1 inch pipe to the socket requires a rubber mallet to secure the fitting. It is a very tight squeeze.

Note: This combination requires using a rubber mallet to force the socket into the 1 inch pipe. It takes some persuation but it will eventually listen. Happy building!
