Who It's For

These undermount slides are aimed at homeowners, cabinetmakers, and remodelers who want a concealed, heavy-duty slide for frameless cabinets and drawers that use a 5/8 in panel. They work well in kitchens, bathrooms, and workshop cabinets where full extension and soft close improve function and everyday convenience.
