Expert Verdict — Reviewed by the SuperArbor Pro Desk

Match the set depth to your cabinet's internal depth minus at least an inch for the back and door clearance; a 22 in. set suits a standard 24 in. deep base cabinet. The 100 lb rating handles file, pot and pantry drawers comfortably. Because these are 3/4 extension self-close runners, items at the back stay less accessible than with full-extension undermounts, so pick the 320M Quick Fix when economy and durability matter more than full reach-in. Keep the cabinet profiles level and parallel or the self-close action will feel uneven.

Fully seat and test-load the assembled drawer before putting heavy contents inside so it cannot disengage from the runners.
