Product Name: Heavy Duty Under-Stairs Storage Drawer Slides with Integrated Angle Brackets (Black Finish)
Product Overview:
Specially engineered for under-stair storage units, deep shoe cabinets, and pull-out pantry towers, this heavy-duty slide maximizes otherwise wasted corner space. Featuring an integrated heavy-duty L-shaped mounting flange with pre-drilled multi-hole patterns, it provides superior bottom-mount rigidity and load distribution. Constructed from high-grade steel with a durable electrophoretic black coating and multi-row solid steel ball bearings, it ensures smooth, sag-free, and quiet operation even under heavy, extended loads.
Key Features:
Integrated L-Bracket Design: Pre-formed mounting flanges ensure straightforward bottom installation, high torsional rigidity, and rock-solid cabinet support.
Heavy-Load & Anti-Sag Performance: Engineered to handle the high leverage and deep stroke demands of full-depth staircase drawers.
Full Space Utilization: Allows deep drawers to pull out effortlessly, making deep storage 100% accessible.
Precision Ball-Bearing Motion: High-hardness solid steel balls deliver ultra-smooth, quiet, and consistent sliding action.
Corrosion-Resistant Black Coating: Sleek electrophoretic finish resists wear and corrosion while complementing modern custom cabinetry.

Installing the Bay Window Slide Rails — Mounting Notes
These are the manufacturer's installation requirements for this rail set. Work through them in order.
Cabinet width and depth. Board width within 1600 mm; depth greater than 350 mm.
Mounting height. The rail mounting height is 50 mm. Leave 51.5 mm of installation height so the assembly clears.
Panel thickness. The installation panel may be 18 mm, 20 mm or 25 mm board.
Overlap. ⚠️ The drawing gives two different overlap figures — the dimension callout reads 100 mm while installation note 4 reads 200 mm. They do not agree, so confirm the correct overlap with the factory before cutting.
Quantities and capacity. One pair consists of two rails. Stated capacity is 50 kg per panel (50KG/片板).
Wide openings. Where board width exceeds 1600 mm, the factory recommends fitting two pairs.
Mounting position. The rails are installed on the two sides of the cabinet body. The manufacturer states this mounting method suits two-tier designs, with the panel fitted at a height of 50 mm. Width is customisable up to 1600 mm.
