Lowell's Cable Benders are cast in iron or aluminum for durability and strength to meet the most demanding requirements.  The "V1" has a 1" opening for easily inserting cables up to 300 MCM.  The "V2" has a 1-5/16" opening for cables up to 600 MCM.  The rounded handle provides a comfortable grip.  The casting has no sharp edges to "cut" the cable jacket.  It is suggested that two handles be used for easier bends.
