Expert Verdict — Reviewed by the SuperArbor Pro Desk
Match the runner length to the cabinet interior depth rather than the drawer front width, and confirm your cabinet opening fits the 1/2 in. side thickness of LEGRABOX. For heavily loaded file or pot drawers, step up to the 773 series 170 lb rating; standard kitchen drawers are well served by the 125 lb series. Tall F and C height sides are ideal for deep storage, while N and M heights keep low-profile fronts clean.
Support the drawer fully when extending to install contents and verify runners are locked before loading heavy items.
