What this runner is

Open a cabinet built on this kind of slide and the drawer sides are bare; the hardware is a pair of runners under the box, out of sight. The PRO634 undermount slide is Würth’s runner for 3/4 inch sides, 100 lb per pair, sold as the pair of runners only. The front locking devices that actually latch the PRO634 undermount slide to the runner are a separate line, because shops pick the specific device for the drawer’s front style.

The drawer box it needs

The drawer box has to be built for the PRO634 undermount slide, not just any box with a notch. Würth publishes the rule: the cabinet opening minus 42 mm inside width, which is the opening minus 5/32 inch outside with 3/4 inch sides. The bottom sits 13 mm (1/2 inch) up from the bottom edge of the sides, each bottom corner of the back gets a notch 35 mm (1-3/8 inch) wide and 13 mm (1/2 inch) tall, maximum, and a 6 mm hook hole goes into the back 7 mm in from the side and 11 mm up. We cut all of that free when you choose the PRO634 undermount slide on our configurator, and we press on the PRO600-FCLIP2D clips before shipping for $5.99.

Face frame or frameless

In a frameless cabinet the PRO634 undermount slide screws straight to the cabinet side. Face frame cabinets use a rear bracket behind the runner instead, which carries the back of the runner to the cabinet back without touching the box at all. The PRO634 undermount slide ships in 9, 12, 15, 18, 21 inch lengths, and the box depth has to match whichever length you order.

Installing it

The PRO634 undermount slide goes on back first: engage the rear hooks in the hook holes, then lower the front until the locking devices click onto the runner. How to install undermount drawer slides walks through that sequence with photos for the PRO634 undermount slide, and once the box is hanging, How to adjust undermount soft close drawer slides covers the height, side to side, and depth adjusters that square up the front.

Order the box to match

Order the box for the PRO634 undermount slide on our custom size dovetail drawer box page: enter the outside width from the rule above, choose Notched and Drilled for Undermount Slides, pick the Würth PRO model, and add the clips.

Questions

What drawer box width do I order for the PRO634 undermount slide?

For the PRO634 undermount slide, use the cabinet opening minus 42 mm inside width, which is the opening minus 5/32 inch outside with 3/4 inch sides. Enter that outside width on the configurator and we cut it exactly; we make no deduction of our own on undermount boxes.

Which clips go with the PRO634 undermount slide?

The PRO600-FCLIP2D front locking device, one left and one right per drawer; that is the match for the PRO634 undermount slide. Clips are not interchangeable between makers or between Tandem and Movento, so match the clip to the runner.
