Hydrofarm ACC8 Active Air Stainless Steel, 8" (Pack of 2) Duct Clamps, 8 inch

It would not fit 10 inch duct would probably fit a 12 inch possibly 11 inch.

Does the job

GREAT!

There's not much to them, but they did what they were supposed to do. I'll be purchasing more.

I installed a duct booster fan and used these clamps to connect the flexible line to the ductwork. They got nice and snug and I have had no problems.

I bought this set of 2 clamps to replace a set of clamps for my 4" dryer vent that were very poorly designed. They only tightened to exactly 4 inches (actually a little less, which is why we had the problem). These continue to tighten as the end of the clamp is pulled through by the turning of the bolt. The bolt is a hex shape with flat head screwdriver option also. Simple, works as advertised.

liked the SS. worked well on my 8" vent hose. Dont know actual strap length but its over 8"...so easy to wrap around hose, insert end and tighten. Nice product. Incidentally...they come in a baggy and you will want to straiten out before use. Rub back of the clamp strap over the edge of a board or similar to get the bend to conform to your requirement. its very easy. don't go wild...steady as go!!

I recently put in 4" insulated hoses and wanted some "breathing room" on my clamps. (Someone's review suggested getting larger clamps because of the insulation). So I got these. They only have a certain amount of adjustability. They did NOT have even enough adjustability to tighten down on the 4" hose. Had to buy other clamps to get the job done. Disappointed. Why can't they perforate just a few more inches to make these more useful?

used them on some 6 inch ducting they work well, nothing wrong with them at all, thanks for a great product!

Product Shipped Fast, Great Quality & value, and as Advertised.

Absolute garbage. 6 inch clamps that don't close up to 6 in. 6in duct tube can't be held by this clamp.

High quality, easy threading clamps. Much better than the clamps in the Hititchi 60 piece assortment I bought. Strong screw bodies on these!

Clampy clamp McClamperson - it clamps
