Fit, Compatibility, and Installation

These concealed undermount slides are designed for both face frame and frameless cabinets. For face frame installations, ensure the inside cabinet depth falls within the 21‑15/16 to 23‑19/32 inch range. For frameless cabinets, the minimum depth is the only constraint. The kit includes everything needed for a clean, professional setup, with rear mounting brackets allowing versatile mounting options.

Quality and Craftsmanship

Blum has been family‑owned since 1952. Many products are made in the USA using a blend of domestic and European components, reflecting a commitment to innovation and craftsmanship. The zinc‑coated steel, concealed roller carriage, and lubricated rollers are chosen to provide long‑lasting performance with a quiet, dependable feel.

Real‑World Uses

In a busy kitchen, these slides glide smoothly as you pull out wide drawers to access pots, pans, or pantry items. In a bathroom vanity or a workshop cabinet, the soft close helps keep drawers quiet and trusted, even after late‑night use. For custom furniture projects, the concealed design preserves a clean interior while offering robust support for everyday loads.
