Test Cap Covers for Attaching Greenhouse Plastic

As described in our video "How to Attach a Cover with Test Caps and Pleats", you can attach your plastic to our Standard Economy Hubs using Test Cap Covers.

These Test Cap Covers can be purchased from Lowes or Home Depot.

On the Lowes site, search for "Charlotte Pipe 4-in Dia PVC Cap Fitting - Item #: 23408 - Model #: PVC 00131 1200"

On the Home Depot site, search for "Test-Tite 4 in. Plastic Plug-On Test Cap (20-Pack, Case of 17) Model # 85015 Internet # 203593757"

4" Test Caps

 

We recommend using these attachments for every hub at the top of the first tier. Use the Fabric Clips for the struts on the equator.

For the 10', 13' and 16' 2v domes that have 10 hubs at the top of the first tier, you will need 20 test caps, and 10 carriage bolts.

For the 24' 3v dome that have 15 hubs at the top of the first tier, you will need 30 test caps, and 15 carriage bolts. If you need to tighten your plastic, you may want to add more test cap connections at the top of the second tier as well.

This technique works best with a single layer of plastic, but one of our customers, Bill Randazzo, has shown us it is possible to attach a layer of plastic to both the inside and outside of the dome using test cap covers. You can see Bill's pictures here. Our hats are off to "Mohawk Bill", who is one awesome dome builder.

By using Bill's technique, you would save money over buying the Dual Ring Hubs, and we support economical solutions.
