X-cosrack Expandable Metal Cabinet Shelf Organizers, Set of 2 Black Powder-Coated Risers

Two metal half-shelves that turn the wasted air above a cabinet stack into usable storage. Each slides open lengthwise to bridge the width you actually have, and the legs telescope so the deck clears whatever sits underneath.

• Adjusts: width from 13.8 in out to 21.6 in, deck height from 5.5 in up to 8.1 in. The two settings move independently.
• Rated load: X-cosrack states 30 lb per shelf, helped by a pair of triangular gussets at the rear of each frame. Spread heavy tins across the deck rather than loading one end.
• Stacking: the two units can sit one above the other for a three-tier run, or go in separate cabinets.
• Finish: black powder-coated iron, wipe-clean and unbothered by cupboard damp.
• Putting it up: four screws per shelf, and the captive nuts are already welded onto the frame, so a screwdriver covers it.
