Holdrite 267J15 Plastic Silencer Clamp, 3/4 Inch, Single pack

You will receive one hanger versus 15 pack as advertised.

The product is great, but the seller is not reliable. I ordered two boxes of 15 clamps each, but only received two single clamps. I used this product before. It holds the pipe securely. The rubber helps reduce noise due to sudden water shutoff. I will probably try to get this from my local hardware store.

Might be a good product, but a pack of one, not 15 is pretty useless.

Instead of fifteen 3/4 inch silencer clamps....you get ONE 1 inch clamp for $32! TOTAL WASTE OF TIME

I received a box today for this item which contained 1 clamp---for $28. This was to be a package of 15. An obvious screw up which garners a 1 star rating (actually less than one star).

Warning - Deceptive advertising - You only get one item for $30 dollars. Holdrite should be ashamed of what they are doing or allowing to be done.

Paid $312 for just 10 pieces of clamp, this is insane. Over $30 each please review before buying this item.

I purchased some of these for an open loop geothermal system that is constantly using water from our well and is all plumbed with copper pipe. The HVAC company installed metal clamps that attached to the wall and ceiling, and when the geothermal system runs the water noise is loud enough that we need to raise our voices if standing next to it, and we could also hear the roaring quite a bit in the rooms next to it as well. The walls and ceiling were basically resonating the roaring noise of the water. After replacing the metal clamps with these, the water noise is 95% GONE. We can stand next to the furnace and the water noise is so minimal that it's no longer an issue and we can talk in a normal voice. In the adjacent rooms we can barely hear the geothermal system running now, which is a huge difference from before. These clamps are pricey, but are well worth it to resolve areas with high water noise. They are of good quality too. The plastic parts have some flex and do not crack, and the inside part seems to be made of silicone which will stand up to the hot water pipes too. Overall a great product!!
