Petiza Ball-Bearing Two-Way Roll-Out Cupboard Shelf, Painted Carbon Steel, White

A single white rack whose lower basket rides on industrial ball-bearing runners rather than plain rails, and pulls from either side. That last detail matters when a waste pipe forces the rack to one half of the cupboard and the door opens from the other.

• Painted carbon steel, white, one rack per order.
• The L-shaped lower basket sets to seven separate heights, so the rack can be tuned to the cupboard rather than the other way round. Fitting works equally well at either side of a cupboard.
• Assembled size, per the seller's own text: 14.95 in by 9.65 in by 15.75 in. The upper tray runs 14 in by 6.3 in and the lower one 15.16 in by 8.66 in. Clearance under the top tray reaches 10.8 in for tall bottles.
• Hollowed shelf surfaces stop puddles forming; wiping down is straightforward.
• Screws and a wrench come along for locking the frame steady, so the basket does not drag the whole rack forward when opened.

Where the source data breaks down. Its capacity field holds 10.8 inches — a length, not a capacity, and the same figure as the bottle clearance above. Its dimension field gives a height of 3.94 in, which cannot describe a rack the seller elsewhere calls 15.75 in tall; we publish the assembled figures and leave the specification height aside. A load of 100 lb is claimed for a frame weighing 2.3 kg; that number is the maker's and we do not present it as a working limit.
