# Drawer slides for 15-series benches: 12 to 24 in slide envelopes and slide-to-upright plates

> How do I mount drawer slides on a T-slot frame?

- Category: Hardware › Framing
- Kind: Hardware

**Exact dimensions.** True size, with no printing tolerance added.

## Notes

- Slide hole patterns differ by maker: the envelope is for space, the plate's 32 mm row suits most; drill your slide's own holes if they differ.
- Leave ½ in (12.7) each side between the drawer box and the plate for the slide.
