An UltraBench UB3648 36" x 48" top and an UltraBench UB2448 24" x 48" top in one order, made to bolt together side by side on their 48" edges into a 4-foot by 5-foot assembly table: one 48" x 60" work surface. Each top is a modular torsion box with a 3/4" dog-hole grid CNC-cut to ±.010". Bolt the two tops together through their 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 4' x 5' assembly table with room for case work and glue-ups, without taking over the whole shop. Made in the USA by Wrecking Ball Tool LLC. Patents pending.
This bundle is the two tops only. Leg kits are optional and sold separately: the UB3648 fits the UltraLeg UL3648 and the UB2448 fits the UltraLeg UL2448, one leg kit per top.

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.
