    DIY Greenhouse Kit​ ​Tips: Are you​ ​building your own greenhouse​? Connect your rails and pipe with ​greenhouse cross connectors​ ​to create a solid frame. Cross connectors firmly latch together two pieces of pipe in the greenhouse structure. Each pack includes two cross connectors. (1 3/8" x 1 3/8") Ideally sized for 1 3/8" top rail fence piping. This greenhouse purlin bracket is commonly used to connect perpendicular piping, ridge poles, purlins to bows or sometimes even a steel support table. Forget the drilling and bolting, it is much easier to use cross connectors especially in overhead greenhouse rail applications.

      • Will you be having more cross connectors in the near future?

        We just put them back in stock :)


      • Could I order a 15 pack of cross connectors?

        We do not offer any other pack sizes at this time.

      • Will these work with 1” schedule 40 PVC? Which has an OD of 1-5/16. Thanks

        We do not recommend using these with schedule 40 PVC. They are specifically designed to clamp around 1 3/8" tubing.
