101-115HSPP White 10pack White Surface Mount Polypropylene Pipe Hanger, American Made for 4 inch Pipe, one-Piece Hanger for Pipes, Cable, or Conduit.

I use these to mount a 4in dryer ducting, I put an insulating foam barrier between the clamp and the duct. Works great and is very sturdy and easy to handle.

Used this to run 4" SD PVC pipe in my shop for dust collector. These worked great!

This is my second order. The first was 2018. They were used to secure the input and output plastic pipes going into my condensing, Combi boiler-hot water heater. The clamps were easy to handle and mount and 3" pipes snapped easily into them. I expected that this would be the end of the story. The clamps were in full sun and weather for 8 years. I notice last week that this exposure almost completely deteriorated the plastic with one on the ground after failing. They needed immediate replacement. In study on this, I learned that Schedule 40 pipe can be degraded by sunlight and weather. To prevent this PAINT THE CLAMPS WITH WHITE SPRAY PAINT after installation. I painted the plastic vent pipe on my roof and it appears to be in very good shape. I expect the paint will protect these new clamps. I am still happy with the purchase as they are so easy to work with. I will do a yearly inspection.

These fit schedule 40 3" PVC perfectly and hold your pipe in place yet allow you to open the clamp if you ever need to repair siding to your home.These are perfect, thank you

I got these brackets to mount 3 inch PVC pipe for a radon mitigation system, and the brackets worked great. I used a single 1/4 inch lag bolt to hold each bracket. As others have pointed out, the arms of the bracket block access to the center mounting hole making installation a bit tedious. What I did was place the bracket where I wanted it and inserted a drill bit (hand held) in the center mounting hole and used the tip of the bit to scratch a mark on the wall. I could then move the bracket aside and drill a hole at the mark. Using hex head lag bolts for mounting, I used a ratchet wrench with a 7/16 socket to tighten the lag bolt. Mounting the brackets that way was easy.I'm including a couple of photos showing a scrap of PVC pipe secured in a clamp.The package has an advisory note suggesting to place the brackets directly below a coupling or fitting in the pipe on vertical runs to keep the pipe from slipping down and that's what I did. The brackets are well made and look good (as good as a bracket can look at least). One side of the bracket has two little plastic nibs (see photo) that I assume are to help pry the bracket open to release the pipe if necessary. You'll want those nibs on the side opposite the coupling or fitting so that bracket sits flush. These served my purpose perfectly.

I bought a set of these in hopes that it would allow me to quickly and easily mount PVC pipe to my ceiling joists and walls for connection to my new dust collector (a high pressure system). They worked incredibly well, and once you get the hang of bending the arms around your impact driver, hanging them was incredibly easy. I snapped a chalk in to keep everything lined up, pre-drilled to make driving the pan head screw easier, and away I went. I was able to pipe my entire workshop in a single afternoon. Well, once I bought all of the correct fittings that is.Also, of the 10, not a single one broke, and I really torqued some of the plastic. I can't imagine what people were doing to make these things break.

Was definitely the right size for my job application. I like how it adjusts, but unfortunately if you open it a little too much, it will break the plastic.

Great product ,holds strong.I combined it with a Simpson strong tie post cap bracket I had laying around and the transition is really nice. When going on the outside of a home aesthetics matter so it's nice to have attractive strong brackets like this available.
