J-4H Series

“XTRA” Heavy-Duty Workbench Performance for High and Hard Workload Applications

The J-4H Series four leg workbench combines the flexibility and customization advantages of the J-4L on our strongest steel frame. Supported by sturdy 3” x 3”, 14-gauge reinforced steel tube legs, the frame structure has been tested for 10,000 lbs. This is the ideal robust workstation solution for heavy duty industrial applications. Available with any of our worksurface materials, including stainless steel and 1.75” thick solid maple.

The J4-H is built to last, with a wide array of available accessories.

Added protection is standard. An aluminum barrier on the underside of laminate worktops and shelves protects against moisture. No other manufacturers offer this standard protection.

Simple, quick assembly. Our workbenches ship ‘knocked down’ for lowest freight cost, and easiest assembly. Comparative data shows significantly lower installation costs for you.
