What do you think? Comfortable and easy to use. One hand grips the handle and releases vacuum with a single finger-touch on the push button release valve. 3 1/4"
OK, but can you trust them not to fail? ( like you never can be sure with duct tape). Does the two" work as well as 4"? If it does, then 2" is the way to go.
I've only had them fall a couple of times, when I first started using them. I'd say it's been a year since I had one fall, and I use them fairly often.
We use wooden wedges for the hood at the back wall... And then Clamps for the sides and front . Clamps are about 1.00 each at home depot and wedges are basically free .
If its a canopy hood we usually tarp all the way from the ceiling to the floor around the hood . We use clamps and attach them to the drop ceiling metal.
If I Cant tarp I Cover the appliances and get out the trusty wet vac..
Duct tape has Never worked for me and it's a waste of time..
Suction cups are to expensive..
I never had the plastic fall ..
14 years and ( No Claims )) I'm Knocking on Wood....
But you know me I will try anything to make the job easy..
Here is a thread I started earlier, with pics. If the surface is clean, and the rubber on the cup is clean they will not come off, the plastic would tear first.
