Z-Bar-Hv-BS-This unique design integrates step bushing (steps down from 0.375" ID to 0.250" ID) mig-welded to the ends of the Z-BAR-HV. The step bushing design allows the bar to lock into a 1/4" diameter wire peg providing uninhibited and superior ground. The 3/8" ID prohibits prevents adhesion to the rack due to excess paint buildup, a common problem with slip-in ends. The closed top bushing design prohibits paint from affecting the ground. Stocked in 30", 40" and 48" lengths. Custom lengths and spacing available by special order. Use Z-HOOKS-HV. Minimum of 25 crossbars per order. Custom quantities available. Please call for pricing.
