I bought 2 pairs of 2.76-2.99 diameter collars to fit 3 inch outdoor volleyball tubes use and I couldn't like the clips and the quality of the stainless steel fittings better for this purpose. which are also made of stainless steel and have good carvings. They are tightened perfectly with an Allen key and drill through the mesh tension perfectly. great discovery instead of hurting the customer or paying the nose of the VB provider.
