Pull-Down Cabinet Shelves: Measure the Clear Opening First

A pull-down shelf labelled for a “600 mm cabinet” still needs a fit check: nominal cabinet width is not necessarily the usable opening.

Measure inside the cabinet

Wellmax's official PTJ018B/D page lists PTJ018D for a 600 mm cabinet, with dimensions 280 × 560 × 650 mm (depth × width × height). Jinnah's direct listing repeats those figures and says to confirm internal clearance. These are listed product dimensions, not a clearance allowance or a guarantee of fit.

Check before drilling

• Measure usable inside width, depth and height at the mounting points; note hinges, shelves, lights, pipes and the closed door's inner face.
• Check both the stored position and the full lowered movement path against nearby obstructions.
• Obtain the exact model's mounting, cabinet and load requirements from the maker or supplier before drilling. Stop if required clearance or fixing details cannot be confirmed.

See the Wellmax model page and Jinnah's direct listing. For fixed shelves rather than a moving basket, see our shelf-support guide.
