PRO Value PRO600 3-Pair Box 27" Soft-Close Full Extension 150 lb Undermount Drawer Slide, Zinc, 0684250553961 3

150 lb Capacity And Full-Extension Concealment in a 27 Inch Undermount

The Pro Value Series PRO600 is a 27 inch ball-bearing undermount drawer slide with integrated soft-close, full extension, and a 150 lb per pair rating — a heavy-duty capacity in a fully concealed package that suits both face-frame and frameless cabinets.

Key Features

• 150 lb weight capacity per pair — handles deep, heavily loaded drawers that would tax a standard 90 to 100 lb undermount.
• Full extension — the entire 27 inch drawer travels out to the cabinet face, putting the back of the box within reach.
• Integrated soft-close — the damper engages near the end of travel and settles the drawer shut quietly, every time.
• Ball-bearing carriage — steel ball bearings in full-length raceways deliver smooth, stable travel even under load.
• Fits face-frame and frameless cabinets — select the rear mounting hardware that matches your cabinet construction.
• For drawer sides from 1/2 to 5/8 inch — compatible with standard dovetailed and doweled drawer boxes built to the PRO600 specification.

Where the 27 Inch Length and 150 lb Rating Earn Their Place

A 27 inch undermount rated 150 lb per pair occupies a distinct position in drawer slide selection. Most concealed undermounts top out at 90 to 110 lb — enough for a standard kitchen drawer, but not for a deep pantry pull-out stocked with canned goods, a base cabinet drawer that doubles as a file tray, or a utility room drawer carrying tools and hardware. At 27 inches of nominal length, this slide pairs with deeper drawer boxes that reach further into a standard base cabinet, maximizing interior storage without sacrificing the clean, hardware-free look that an undermount provides. Full extension means the contents at the very back of the box are reachable without reaching into the cabinet — a practical requirement in any deep drawer application.

Steel, Ball Bearings, and a Zinc Finish Built for Service

The PRO600 runs on steel ball bearings rather than the nylon rollers found in economy roller slides, which keeps travel precise and consistent as drawer weight increases. Steel construction throughout the slide body provides the structural backbone the 150 lb rating demands. The zinc finish protects the steel members through years of indoor use. Because the slide mounts concealed beneath the drawer box, the finish is functional rather than decorative — it will not be visible once the drawer is installed.

Who Reaches for This Slide

Cabinet shops and contractors working on pantry bases, deep utility drawers, or any application where a standard-capacity undermount would be undersized will find the PRO600's 150 lb rating the deciding factor. Homeowners building a laundry room or workshop cabinet with a 27 inch drawer depth get the same concealed, soft-close result without stepping up to a premium brand's price point. The compatibility with both face-frame and frameless construction makes it a single-SKU solution across traditional American and modern European cabinet builds on the same project.

A Concealed Slide Sized for the Job, Not Just the Opening

When the drawer is deep, the load is real, and the finished look still matters, the PRO600 delivers the capacity and full extension that smaller undermounts cannot — without making a visible compromise in the cabinet.
