Greenhouse Clamps

Greenhouse clamps and compatible fittings secure coverings or connect parts of PVC and other framed growing structures. This collection includes snap clamps and structural fittings in multiple sizes, so accurate measurement is essential before ordering.

Selecting clamps and fittings

  • Measure the actual outside diameter of the tubing or pipe.
  • Confirm whether the part is intended to hold fabric, join frame sections, or serve another specific function.
  • Match the fastener to the covering material and expected wind exposure.
  • Inspect seasonal installations and replace parts that are cracked, loose, or distorted.

Clamps do not substitute for appropriate structural design or anchoring. Follow the product directions and any greenhouse manufacturer requirements. Browse related Greenhouse Accessories, Greenhouse Plastic, and Shade Fabric.
