These rods come stock in the AG Bender 7 and can be retrofitted into the AG Bender 6 (which came stock with Delrin™ Contact Rods).
Teflon™ rods work well with PVC-coated wire mesh, which is the most common type on the market. Manufacturers like Heyco, Spiffy Solar, Omni and mysquirrelguard.com all use 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.
