Fasteners and Hardware — FAQ
Can undermount slides handle stone countertops?
Yes, but only heavy-duty models rated 200+ lbs per pair. Standard 100 lb slides will sag under stone's weight. Always use two slide pairs per drawer and derate capacity by 20% for safety.
Why do my soft-close slides stop working after 6 months?
Dust accumulation in the mechanism is the usual culprit. Clean rails quarterly with compressed air. Low-quality slides use weak springs that fatigue—opt for hydraulic systems like BLUMOTION for longevity.
How much clearance do undermount slides need?
Minimum 1/2" side clearance and 1" rear clearance for full extension. Measure cabinet interior before ordering—some '21-inch' slides require 22" of cabinet depth due to mounting brackets.
Are soft-close slides worth the extra cost?
Absolutely for contractor work. They prevent broken dishes, reduce callbacks for noisy drawers, and add perceived value. The $5-10 premium per slide pays for itself in repeat business from satisfied clients.
Can I mix different slide brands in one project?
Never. Different extension mechanisms cause misalignment and binding. Even identical load ratings vary in pullout force. Consistency prevents callbacks—stick to one proven brand per job.
Why do my new slides feel stiff?
Factory lubricant thickens in cold temps. Cycle drawers 20+ times to warm the grease. If stiffness persists, check for mounting screws protruding into the slide path—a common installation error.
