PRO Value PRO600 Front Locking Device, Right Hand, Black, PROOTSSL04R

Black Right-Hand 3D Front Locking Device for PRO 600 Undermount Slides

This is the right-hand front locking device for the PRO 600 undermount drawer slide series, with 3D adjustment built into the flange so the drawer front can be trued in height, side, and depth after the box is hung.

Key Features

• 3D adjustment — height, side, and depth can all be dialed in after installation, so minor misalignment gets corrected at the locking device rather than by rehanging the drawer.
• Height adjustment of +3 mm — raises the drawer front to close an uneven gap at the top of the opening.
• Side adjustment of +/- 1.5 mm — shifts the front left or right to center it in the opening.
• Depth adjustment of +3.5 mm — pulls the front closer to or seats it flush with the cabinet face.
• Flanged design — the flange provides a positive seat under the drawer box front, keeping the connection stable through repeated cycles.
• Right-hand orientation — this is a single right-hand device; pair it with the matching left-hand device to complete one drawer installation.

Where This Locking Device Fits the Work

In production shops running PRO 600 undermount slides, the front locking device is the final step between a hung drawer and a finished-looking face. When a row of drawer fronts comes out with one sitting a millimeter too high or a face frame gap that reads slightly off-center, adjusting the locking device is faster than pulling the drawer and reshimming the box. The 3D range — height, side, and depth together — covers most of the fit problems that show up after the box is in and the front is mounted. This right-hand unit handles the passenger side of the drawer; order the left-hand version alongside it for every drawer in the run.

Material and Finish

The device is molded in black plastic, which keeps weight low at the front connection point and resists the corrosion that would affect a metal clip in a damp cabinet environment. The black finish reads visually quiet under a wood drawer box, and it is consistent with the Black color family across PRO 600 accessories. Plastic construction also means the flange can flex slightly during installation without damaging the drawer bottom or front — a practical advantage when fitting hundreds of drawers in a production run.

Who Needs This Part

This locking device is the right choice for cabinet shops already running PRO 600 undermount slides and sourcing replacement or additional locking devices to stock against a production run. It is also the part to reach for when a drawer front on an existing PRO 600 installation has drifted out of alignment and the locking device needs to be swapped rather than adjusted further. Homeowners doing a single cabinet repair and contractors specifying a new kitchen can both use it — the installation is tool-free at the clip itself once the drawer box is on the slides. This device is PRO 600 series-specific and is not interchangeable with locking devices from other undermount systems or other series in the Pro Value line.

The Right Part Keeps the Run Moving

Stocking the correct right-hand locking device for your PRO 600 slides means a misaligned drawer front is a two-minute correction, not a callbacks job — and that is the kind of detail that keeps a production schedule on track.
