      QUESTIONS & ANSWERS

      Ask a Question
      • What size of clamps I need for 1/2” pvc pipe

        You need 3/4" clamps for 1/2" PVC Schedule 40 pipe. You can find this info here: https://www.bootstrapfarmer.com/products/snap-clamps

      • How long are the 3/4 " clamps?

        They are 5 1/2 inches long.

      • What size of Green House Snap on Clamps do I order for 1/2" PVC? Thank you.

        You would need the clamps labled as 1/2 inch.

      • I have three “green house” structure made out of 1” EMT. They cover raised bed planters I made a few years ago. In the early spring and late fall i cover them with plastic to extend my growing season. Will your snap clamp work over 1” EMT? Currently I am using 1” plastic clamps from harbor freight to hold the plastic on, which it really does not do well. Thanks.

        The clamps we have will be too small for 1" EMT unfortunately.  We only have ones for 1/2" and 3/4".

      • 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!

      • 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

      Well-Made Product

      We purchased 100 of the greenhouse snap on clamps and have used them for about 2-3 weeks. They are easy to get on and off and hold onto the pvc tubing well. No blowing off in the wind. We're using them to hold on insect netting on our raised beds.

      Love these for my garden covered rows

      I have several covered rows in my garden. Until last year I used the usual white plastic clamps and was never happy with them. The sharp corners tore the agribon and they were really hard to remove when I needed to lift the fabric. Bought my first pack of these clamps last year. Came back for two more packs this year. Much easier to put on and pull off yet the cloth stays out even in strong wind. With the rounded edges, the fabric no longer tears! I was able to re-use a large piece of agribon because it survived the season intact. Highly recommend the clamps. Note - shipping for two packs of clamps was $19 which I thought was rather high.
