Expandable Shelf Tray, Telescopes 11.8-49.2 in, Carbon Steel

A shelf that is deeper or wider than the things you store on it wastes space. This flat carbon-steel tray rests on the shelf you already have and telescopes out to the width of the opening, so the gap above or beside it becomes usable storage. A second tray stacks on top to make two levels in one shelf.

The tray adjusts tool-free across five width ranges, from 11.8 in to 49.2 in. It slides out to the width you measured and locks in place. Depth options are 9.4 in (24 cm), 13.8 in (35 cm) and 16.5 in (42 cm). Height options are not stated by the maker. The material is carbon steel: thick steel pipes with a double-row bracket.

Best for: closets and wardrobes, shoe cabinets, cupboards and pantries. It sits on a flat, level shelf and needs no drilling, no stitching and no pasting. The supplied double-row bracket and three-point support keep it steady. This is not a kitchen or bathroom product.

Not ideal for: openings narrower than 11.8 in, wire or glass shelves that flex, or hanging and wall-mounted setups. The maker does not publish a load rating, so we cannot state one.

How to choose: Measure the width of the opening at the shelf. Measure the shelf depth. Check that the shelf is flat and level and that it does not flex. Pick the width range that covers your opening and the depth that matches your shelf. If your opening is under 11.8 in, this tray will not fit.

In the box: One telescopic tray, one double-row bracket, three-point support hardware. Assembly is none: the tray telescopes out to the width and locks.
