Product review (5 stars): Great product.  Just what you need and quality construction, too.
Great product.  Just what you need for a dryer hookup with clamp and adapter, too. Nice quality.  I was installing a Fantech secondary dryer filter downstream of my Samsung dryer after discovering that the lint filter in the dryer isn't worth a tinkers damn and lots of lint is getting past it.  This was never a problem on my old dryer but is on my new dryer, especially since it vents into the attic.  Nothing like vacuuming dryer lint out of your attic on a hot day.  So, I added the secondary filter box as Phase I of dryer vent mods and will add a soffit vent next.

Meanwhile I needed some accessory parts and pieces so I bought this.  It arrived really quickly; just in the nick of time, and as it turned out, the manufacturer of the dryer lint box did not include all the parts and pieces, but this kit includes a nice quality hose that is preshaped for ease of connection, along with a sleeve adapter (which was just what I needed) and a clamp.  perfect for adding a single dryer.  In my case, I needed one extra set of clamps and some Shurtape aluminum duct tape to finish the job (and lots of patience), but it turned out great, thanks to this product.
