Review on Stainless Steel Pipe Clamps With Rubber Cushion - LOKMAN 46-Piece Assortment Kit In 6 Different Sizes: 1/2'' 1'' 1.25'' 1.5'' 1.75'' 2'' For Insulated Cable Management by Damian Grotting

I recently bought a few sizes of Lokman clamps, for multiple applications. I found that they do run a little smaller than the nominal diameter -- 1/8" less than nominal diameter in the smaller sizes. So best to order a slightly larger nominal diameter than you actually need. They are very durable. Heavy enough metal so they are not too easy to bend. Ample amount of rubber.I installed some on my utility trailer 10-12 years ago, and they are still doing the job. Rubber is somewhat degraded, but still in place, which is understandable for a trailer that has been out in the weather for that long.
