These rods are compatible with R6 and R7 AG Benders. They are made of a harder material than our stock Teflon™ Contact Rods, allowing powder-coated wire mesh to flow through the machine with minimal effort. Powder-coated wire mesh (also referred to as “poly coat” or “polyester”) is more rigid, durable and long-lasting than PVC-coated mesh. Learn more about different types of wire mesh. We strongly recommend using the proper Contact Rods for your wire mesh, as this greatly reduces the force required to pull mesh through the Bender. The rods can be swapped into your machine in as little as 5 minutes using these instructions.
