48x48 UltraBench Square Bundle

$598.99 USD

Sale Sold out

Two UltraBench UB2448 tops in one order, made to bolt together side by side into a 4-foot-square assembly table: one 48" 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 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 square assembly table you can work from all four sides, with room for drawer boxes, glue-ups, and small case work. 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: both tops fit the UltraLeg UL2448 steel leg kit, one leg kit per top.

What's included

  • 2 x UltraBench UB2448 24" x 48" modular workbench top kits: each with 9 CNC-cut furniture-grade plywood part types with hardwood cores, and 40 #10 x 2-1/2" T25 Torx wood screws

What you'll need

  • About 16 oz of wood glue, 8 oz per top (not included)

  • SAE wrenches or sockets (7/16", 9/16", 3/4")

Grows with your shop

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

Lifetime guarantee. If you are ever unhappy with your UltraBench system, send us a message and we will make it right.
