Circo Innovations Aluminum Snap-On Hinge, 3/4", Silver

Bought these to add a gate at the top of the stairs leading from the lake house up to the garage/parking level. There was an existing stair railing made of metal pipe. The hinges snap on easily and stay in place. We made a gate using black furniture grade sch 40 pvc (Formufit from Home Depot), and filled in the frame with black garden netting using zip ties. After lining the sides of our terraced yard with small, cheap garden fencing (they could probably jump over it, but they don't know that and can't read reviews), this gate was the final piece needed to keep my little poodles in our yard. Now I can take them out without having to leash them up every time. Yay! These were a good buy! P.S. Just pay attention to the dimensions. These snap onto 3/4 inch pvc or metal pipe (which has an outer diameter of just over 1 inch).
