The Model DD-7 is part of our line of DD Series bending machines. It is a dedicated bender for bending solid round bar stock. It offers an alternative to our standard line of compression benders. It is a rotary draw bender that is designed to bend solid round bar stock for anchor bolts, J bolts, U bolts, eye bolts and other products that use bent solid round bar stock. It is not as versatile as our standard line of benders. But it does offer a less expensive option for bending solid round bar stock. Our full line of DD Series benders have the capacity to bend 1/4 IN OD- 3 IN OD A-36, mild steel, solid round bar stock.
