The Pro Value Series PRO 634 is a 15 inch soft-close full-extension undermount drawer slide built for 3/4 inch drawer sides, rated 100 lb per pair, and compatible with both face-frame and frameless cabinets. Locking devices and rear mounting brackets ship in the box, so you have what you need to complete the install without a separate accessory order.
At 15 inches, this slide is the right call for shallower base drawers, bathroom vanity drawers, and smaller cabinet boxes where a longer slide would crowd the cabinet. It suits shops building with 3/4 inch hardwood sides or thicker plywood, a common choice in face-frame cabinetry where solid-wood drawer boxes are standard. The full-extension travel means items stored at the very back of the drawer come fully to hand, which matters more in a compact drawer than a deep one. The included rear brackets remove the most frequently missed part from the ordering checklist for face-frame work.
The PRO 634 runs on steel members with a zinc finish, suited for indoor cabinetry service. The drawer box must be built to the PRO 634 specification for this length: nominal 15 inch box length, box width sized for the slide's side clearance, bottom recess, rear notch, and drilling for the included 2D locking devices. The 2D locking devices allow height and side adjustment at the front, letting the installer true up the drawer face after the box is seated. The rear mounting brackets are series-specific to the PRO 634 and do not interchange with brackets from other undermount lines.
Cabinet shops running face-frame production with 3/4 inch solid-wood drawer boxes will find the PRO 634 a practical fit: the included brackets and locking devices reduce what needs to be sourced separately, and the 100 lb rating covers most residential drawer loads at this size. It also works for frameless builds where 3/4 inch box material is already the shop standard. Homeowners retrofitting a single vanity or bath cabinet with concealed slides get a complete hardware set without navigating accessory compatibility across multiple SKUs.
Yes. The 2D locking devices and rear mounting brackets are included in the box. In a face-frame cabinet, the rear brackets support the back end of the slide behind the frame. No additional PRO 634 accessories are required for a standard face-frame installation.
This model is engineered for drawer sides up to 3/4 inch (19mm). For 5/8 inch (16mm) drawer sides, choose the 16mm version of the PRO Value undermount line — the two versions are separate models and do not interchange.
No. The drawer box must be built to the PRO 634 specification: 15 inch nominal length, correct width for the slide's side clearance, a bottom recess, a rear notch, and drilling for the locking devices. An off-spec box will not seat properly on an undermount slide.
The included locking devices allow the installer to fine-tune the drawer front in two directions — height and side — after the drawer is hung. This makes it straightforward to align reveal lines on a run of drawers without repositioning the box.
Per pair. That is the standard for undermount slide ratings across the catalog, and 100 lb per pair covers typical residential and light commercial drawer loads at this length.
The PRO 634 in 15 inches packages the hardware a face-frame or frameless install actually needs — slide, locking devices, and rear brackets — into one SKU, so the drawer goes in without a follow-up parts order.
