Duct Clamps - Adjustable
You've got the ducting all figured out - now how do you keep it where you want it to be?
Adjustable duct clamps keep all your connections in place. With the simple twist of the screwdriver these clamps will hold on tight.
Simply place the clamp over the duct hose (loosely) before you connect the duct hose to your reflector, fan, etc. Once the duct hose is properly placed, align the clamp over the area that fits around the flange, then tighten snugly.
Remember to place the adjusting screw in a position where you can easily reach it with a screwdriver to avoid frustration. Measurements are by diameter:
