does this clamp work on poly tarps?
We use the clamps to secure our greenhouse plastic to EMT pipes in order to rollup the sides of our greenhouse. If you are using 1/2" EMT piping the 1/2" snap clamp should suffice or if 3/4" the 3/4" clamp would work.
Since PVC and greenhouse poly react and cause the greenhouse film to degrade, won't these cause a reaction? I think they're an awesome idea. I'm just concerned about a reaction between the greenhouse snap clamp and the greenhouse plastic. I'm using 1/2 inch emt and covering it with 4 mil greenhouse plastic to make poly low tunnels.
Good question! You will have no issues with these particular applications. The reaction comes from PVC hoops rubbing on plastic. The PVC wire and the snap clamps remain in place, and cause no reaction. You will have no issues with our products for the intended applications!
What size greenhouse clamp is correct for 1/2 inch pvc pipe with 6 mil plastic? Your size chart does not make sense.
If this is 1/2 OD pvc you will need the 3/4 inch clamp.
which greenhouse clamps are suited for the standard top rail fencing hoops? Looking to do my roll up side. Thanks!
We dont use the clamps ont the rail fencing. We secure that with the spring wire and channel. We do use 3/4" snap on clamps for the 3/4" EMT that is used on the roll up side
