Review on ISPINNER 2Pcs 2.5 Inch Key-Type 304 Stainless Steel Worm Gear Hose Clamps, Adjustable Size Range 40-64Mm Clamps For Dryer Vent, Dust Collector And Automotive by Mike Shah

After reading reviews on how some verified buyers had difficulty installing 4-inch hose clamps on their 4-inch dryer vent. I bought the 5-inch ones and am glad I did. Why? These blue plastic toggles on these clamps makes installation of flexible aluminum hose from 4-inch dryer vent to 4-inch wall exhaust pipe easy. Now it’s possible to pull my dryer away from the wall to vacuum behind dryer without the flexible aluminum dryer hose detaching from either the dryer or the wall.
