T-slot bench tops for 15-series frames: 24 × 30 to 36 × 96 in, ¾ and 1 in thick
How do I bolt a worktop to a 1515 T-slot frame? · Hardware · basis: Xem Studio design: flat panels whose holes sit on the centre lines of a 1.5 in rail running under every edge (0.75 in in from each edge), counterbored for a 5/16-18 socket head cap screw into a slide-in T-nut
Exact dimensions. True size, with no printing tolerance added.

- 14 in table
Notes
- Edges flush with the frame's outer faces when the frame's outside size equals the top. Holes no more than 12 in apart along each edge; add a cross rail for longer spans and drill its holes from the frame.
