Two UltraBench UB3648 tops and two UltraLeg UL3648 steel leg kits in one order, one leg kit per top, made to bolt together side by side into one 6-foot by 4-foot mobile assembly island: one 72" x 48" work surface. Each top is a modular torsion box with a 3/4" dog-hole grid CNC-cut to ±.010". Bolt the two benches together through the tops' mounting holes (joining bolts not included, see What you'll need) and the dog-hole grid carries straight across the joint. That gives you a big assembly island for cabinet and case work, with room to work from every side. Made in the USA by Wrecking Ball Tool LLC. Patents pending.

Set both benches to the same working height, anywhere from 32" to 43" during assembly, roll them where you need them, and lock the casters down to work.

Grows with your shop

Every UltraBench top shares the same 3/4" dog-hole grid. Start with this setup, then add more benches later, end to end, L-shaped, or as an island, and the grid stays continuous across every seam.
