1-1/4" OD 3 Way plastic corner for cubes and rectangles with spring buttons Set of 4

Our 1-1/4" plastic molded 3 way corner is designed to work with our 1-1/4" OD x .049" wall round tubing. This 3 way corner can be used to build aluminum tubing cubes, aluminum tubing rectangles, and other 3D structures and rectangular prisms. This 1-1/4" plastic cube corner works well with Testrite's 0.049" wall 1-1/4" OD round tubing with a good fit with only a small amount of play, enabling 90 degree connections between two 1.25" outside diameter tubes. This 1-1/4" plastic rectangular prism corner has a max thickness at the part that goes into the tube of 1.13" and is tapered up to that, meaning it should fit onto .060" tubing, although a rubber mallet may be required, and the fit may depend on the quality and consistency of your tubing wall and ovality. If you intend to use these corners with .060" tubing, we recommend purchasing a sample first to test. This 1-1/4" plastic corner can work with Testrite's .038" wall 1.25" OD tubing when we apply indentation rings to our tubing. While
