left hand adjustable rear mount bracket from Grass America serves as a rear mount adjustable adapter, so it supports drawer slide alignment at the back of the cabinet when a left side connection is required. The left hand design focuses this bracket on installations where the slide must anchor on the cabinet's left rear wall, which helps keep your layout consistent across multiple drawer bays. The rear mount function positions the support at the back rather than along the side, so it works in layouts where only the rear panel can accept a mounting point. The adjustable nature of this bracket allows fine-tuning the slide position relative to the cabinet, which helps align drawers so they run smoothly in use. The white finish identifies this specific version and can coordinate with white cabinet interiors where color consistency matters during a visible installation.
This rear mount adjustable adapter is described as screw-on, so it is intended to be fixed to the cabinet using screws during installation, giving the drawer slide a stable rear support point. The left hand configuration focuses its use on the cabinet's left rear corner, which helps keep your installation repeatable when laying out multiple drawers in a bank. The adjustable capability supports small position changes after fastening, which lets you tune drawer slide alignment without rebuilding the cabinet. Its white finish provides a consistent look wherever the rear of the hardware is visible during drawer operation, which can be useful in open or glass-front cabinet designs.
This left hand adjustable rear mount bracket works as a rear mount adjustable adapter within a drawer slide setup, so it takes on the role of supporting the slide at the back of the cabinet on the left side. In a typical drawer run, the cabinet rear panel often provides the most stable surface; this bracket translates that stability into a fixed point for the slide. The screw-on reference indicates that it relies on screw fastening to link bracket and cabinet, creating a rigid connection once positioned. Because it is designated left hand, it is organized to match layouts where the slide hardware on the left side of the drawer requires a specific bracket geometry at the rear. The white finish means this part can visually integrate into light-colored cabinet interiors, which helps keep the focus on the drawer fronts rather than the hardware behind them.
The adjustable function built into this rear mount adapter allows small changes to the drawer slide position after the screw-on fastening is set, so you can refine how the drawer sits in the opening. This adjustability is valuable when cabinet dimensions or construction tolerances create slight variation between openings, because the bracket can help compensate at the rear instead of altering the cabinet. By using a left hand adjustable rear mount bracket, you give the left slide a controlled adjustment point that mirrors how you are supporting the right side of the drawer run.
