10 Set 1-3/8" Greenhouse Cross Grid Connector, Pipe Clamps for Chain Link Fence

These cross connecting brackets worked great. Some reviews complained of fastener quality. Unless you were over torquing the fasteners, not sure how others experienced issues with fasteners? Bolts and nuts that came with the brackets were adequate, did the job. Would purchase again!

It fits 1-3/8 in. Galvanized Metal Top Rail. Good quality.

We needed to protect our 20' LOA, 8' Beam Ply on Frame Boat we built in our backyard so we constructed a metal pipe quonset hut that measures 12' wide by 20' long by 6 1/2' high. Using the OTTFF Cross Grid Pipe Connector Clamps (for 1 3/8" diameter pipe) made the building of the hut an easier task. Working alone, the rail clamping took a few hours. After aligning the 5 arched to the topmost rail we covered the pipe frame with a heavy duty white canopy to protect the boat from the harsh Florida Sun and humid environment. We highly recommend the OTTFF Cross Grid Pipe Connector Clamps because they are a quality product, hold fast and can do the job.

I use these for making perpendicular connections between regular fence pipe to EMT conduit or 1" PVC. I have not found anything else affordable that would do this. These seems to hold up fine. The screws kept coming apart so I went to the hardware store and spent another $10. Those are solid.

Perfect for hoophouse purlins. Easy to assemble. Quality is excellent. Best prices too.

Clamps are great, but the included nuts and bolts are trash. The bolts are M6x20 (not sure why the product info says M5) and they're too short. They need to be at least M6x30 with M6x40 the optimal length. No washers (either flat or locking) and the nuts are not nylon lock nuts. Really? If you're going to provide a standard nut, then throw in locking washers. But nylon lock nuts would be the best solution. Love the clamps; they will work perfectly. Not at all happy that I had to buy decent (additional) attaching hardware to adequately complete the project. 3 stars.

I used these connectors to construct shelving in my basement. I like the connectors because they are solid and keep the tubing for the shelves in place. The only drawback if there is one is that the connector is attached using four bolts and nuts. I would recommend a magnetic racket ad Phillips screwdriver to make the assembly go faster and cut down on dropping bolts or nuts.

The clamps work as shown in photos, they will also work with smaller diameter pipes if needed. The included screws could be a longer, and the head little larger using hex head bolts with the clamps make the job simpler and faster for tightening. Very awkward to use if connecting a diagonal pipe to a straight pipe, only best for pipes that are 90 degrees to each other.
