Have You Ever Considered Building Peristyles Out Of PVC? The issue up to now has been that they do not make a fitting that can join PVC in a triangle shape... until now! Check out my latest invention! https://youtu.be/X5hQpLMne24 I have invented a special corner fitting that can make a triangle shape using 1 1/2 PVC piping. I can also create almost any other type of fitting and/or design on my 3D printers The Peristyle Kit comes complete with 6 Custom Corner Fittings 3 Caster Adapter Plates The caster adapter plate fits into the bottom of the PVC pipe so you can easily attach either the standard steel swivel caster or the single stem office chair caster. If you require more than one set then message me please
