12 Sets 90 Degree 3 Way Cross Pipe Connector Clamps, Fits 1/2" EMT Conduit

These were perfect for what I needed. Building a garden trellis and needed these to combine conduit pipes. Great fit

I ordered these for a garden frame for tomato plants, made with 1/2 inch EMT conduit. I knew I’d need to use the shims. What I didn’t know is how lousy the construct would be, how loose and bendy, even after I got all the corners assembled. There was so much torque and toggle that it wouldn’t stay square. If you tighten the nut and bolt on each side, you don’t get uniform closure around the pipe end; you get a gap, instead. And then that allows the pipe to shift back and forth. I chose these because they were priced better than the alternatives. Big mistake. I spent more money in the end and went through a lot of hassle; I had to drill holes through the pipes and add screws to keep them from wobbling so badly. Even that wasn’t enough to make a frame I could actually position into place, so I had to add cross braces and buy connectors for those. I have seen countless examples of the simple frame I wanted to build in online videos and photos. None of them used cross braces, because it was just a simple rectangle structure that wasn’t enormous or anything, just for an 8x4 bed. But I had to use five cross bars to achieve stability—two on each short side, and one over the top—with these horrible corner clamps. And that was after putting three screws in each corner, one per pipe, just to keep the bracket in place. Worse yet, as I maneuvered the construct gently, to access other holes, I watched in horror as the metal just… bent. It was no longer forming a 90 degree angle, more like a 70. And I was able to take two pliers and bend it back fairly easily, which was just as bad. I almost returned these, but once I had gone through the trouble of screwing them to the pipes and adding cross bars everywhere, it was not worth taking it all apart. But I do know I will never buy this product again, and I’m concerned about how I can use the four pieces that remain, after my two bed frames, since they are so fiddly and annoying, not at all stiff enough to stand up to the leverage of conduit structures. Should’ve just gone with a more expensive option, because I would have spent a lot less in the end, and not had to drill 24 holes through metal pipes. This was much more painful than it needed to be. And don’t get me started on the crappy quality of the shims…

Used these to build an RV cover, quality was great and functional! Would buy again!

I was able to use these to make two vegetable garden shade structures. I learned a couple of things in the process such as 1) best to use a flat level surface to assemble the sections. 2) loosely thread the two sides of the connector first, THEN insert both pipe sections and tighten both sides. 3) it works best to then insert a set screw or hex head self-tapping metal screw through the other hole. I definitely had the issue at first where I thought it was all assembled and it felt tight and did not twist. The literally within seconds of trying to move the assemble into place, it all fell apart! I tried set screws from Amazon first and the description and video accompanying this product contradict each other on the size. One says M10 and the other a # which I don't remember. I bought and tried both and neither would thread. I ended up buying and using 1-inch #8 self tapping hex head metal screws. These didn't really self tap and I ruined a couple of drill bits making pilot holes but at least the dang thing holds together now.

Nice product.

They work good for 3/4 but the shims are of no use for 1/2" they push the connector apart

They bend easy with wind On the clip.

Good product, fair price

ottimo prodotto
