TIG rod holder brackets

These brackets are made to hold PVC tubing 50mm ID 56 OD but there is a little room to move down a size maybe 1mm on the OD for TIG welding filler rod.

Top bracket uses 6mm bolts which can use a nut on the back but M6 threads into the plastic fine. Bottom bracket is just for the tube to sit in, no bolts required. Both brackets have a slot to fit over 2-3mm steel or alloy flat bar that I have welded to my welding bench.
