The PRO50 Series left-hand rear mounting socket gives the back end of a drawer slide a solid anchor point in face-frame cabinet construction, where the cabinet side does not extend flush to the frame opening. This plastic screw-on socket is the left-side component of the rear support pair that keeps PRO50 Series slides properly aligned from front to back.
Face-frame cabinets set the cabinet box back from the front frame, which means a slide mounted at the front has nothing to grab onto at the rear of the cabinet side. The rear mounting socket closes that gap. It attaches to the back of the cabinet interior and receives the tail of the PRO50 Series slide, holding the slide level and preventing the back end from dropping or shifting under a loaded drawer. Without rear support in this construction, the slide can rack, bind, or pull away from the cabinet wall over time. This socket is the left-side piece; a right-hand socket is required for the opposite side to complete the rear support pair.
The socket is molded in white plastic — a practical choice for an interior component that stays hidden once the drawer is installed. Plastic keeps the socket light, resists moisture better than bare steel, and will not scratch the cabinet interior during installation. The white finish blends into painted interiors and white melamine cabinet boxes without standing out. Screw-on mounting means no special tooling: position the socket, drive the screws, and the slide drops in.
Cabinet shops and installers running PRO50 Series slides into face-frame cabinets are the primary buyers. If a project uses frameless construction, rear mounting sockets are not required because the slide mounts directly to the flush cabinet side — this socket is for face-frame work only. It is also useful as a replacement when an existing socket is lost or damaged during a retrofit or remodel. Order one left-hand and one right-hand socket per drawer to complete the rear support for a single slide pair.
No. Rear mounting sockets are engineered to the geometry of a specific slide series. This socket is designed for PRO50 Series slides and is not confirmed to fit other brands or series.
Not typically. In frameless construction the slide screws directly to the flat cabinet side panel, so there is no unsupported rear end. Rear sockets are a face-frame installation requirement.
Two — one left-hand and one right-hand socket, one per slide. This listing covers the left-hand side only; add the right-hand socket separately to complete the pair.
Yes, it is handed. This is the left-hand socket and it is designed for the left side of the cabinet. Installing a left-hand socket on the right side will cause a fitment problem. Order one of each orientation per drawer.
A rear mounting socket is a small component with an outsized effect on slide performance — a properly supported slide tracks smoothly, holds its alignment, and extends the life of the whole drawer system. Get the left-hand socket in place alongside its right-hand counterpart and the PRO50 Series slide has the rear support it needs to do its job.
