<b>IMPORTANT: MEASURE CABINET BEFORE PURCHASE | ADJUSTABLE FOR PIPE OBSTACLES<b>: Please watch our installation video for reference. This under‑sink shelf features telescopic rods for length adjustment, multi‑position mounting holes for height adjustment, and a removable side panel to bypass drain pipes. If you are unsure whether your cabinet fits, we DO NOT recommend purchasing. Measure cabinet inner width, height & depth; account for drainpipes, cabinet dividers and plumbing parts before ordering to avoid return due to poor fit.

Precise Size & Fit Guide: Fixed width: 11.2" (28.5cm). Expandable length: 16.5"–30.7". Adjustable height: 13.19"–16.73". Max size: 30.7"×11.2"×16.73", Min size: 16.5"×11.2"×13.19". Please measure your cabinet’s inner width/height first to avoid mismatch. Note: Due to manual measurement, there may be a difference of a few millimeters！

Expandable & Customizable Fit: Damping telescopic rails adjust length from 16.5" to 30.7" to fit different cabinet widths. Refer to the second and third pictures: 3 height options (a/b/c hole) for the 2nd tier and 2 (d/e hole) for the 1st tier. Removable panels easily bypass U/P-shaped sink pipes for a perfect fit. Flexible layout adapts to most residential under‑sink spaces. Multiple height positions create variable shelf clearance for tall bottles and cleaning supplies. Detachable side panels help bypass U‑tubes, water filters and pipe protrusions, making full use of otherwise wasted cabinet room.
