## Description

Upgrade your cabinetry with Blum TANDEM plus BLUMOTION concealed undermount runners, also called drawer slides or glides, designed for a clean look and smooth performance. These 21-inch runners provide full-extension access so you can reach every item and maximize storage space. Perfect for kitchens, bathrooms and custom furniture projects. Before purchasing, check your measurements to ensure a perfect fit. TANDEM runners follow the standard American cabinet depth system. A 21-inch runner pairs with a 21-inch drawer length. For face frame cabinets using rear mounting brackets, your inside cabinet depth should be at least 21-15/16 inches and no more than 23-19/32 inches. For frameless cabinets, only the minimum depth matters. These runners are built for wood drawers and support up to 100 pounds, making them ideal for deep or wide drawers that hold heavy items. Enjoy the luxury of soft close every time. Integrated BLUMOTION technology ensures drawers close gently and quietly, protecting your cabinetry and eliminating slamming. Optional bottom mount holes provide flexibility for attaching runners to the cabinet bottom. Installation is simple, and tool-free height and tilt adjustments let you fine-tune drawer alignment for professional results. Each kit includes everything you need for face frame or frameless cabinets: left and right runners, locking devices, rear mounting brackets and screws. Crafted from zinc-coated steel with a concealed roller carriage and lubricated rollers, TANDEM runners deliver durability and smooth operation for years to come. Proudly manufactured in our North Carolina facility using high-quality domestic and European components, Blum combines innovation with craftsmanship you can trust.

Review: Great slides - Wish they had come with the right screws - Pros: These Blum slides are worth the money, and this was a good deal on six of them. So much cooler than side-mount drawer slides. The slides are reasonably forgiving in terms of alignment. The action is smooth, and the self-close is a wonder of engineering design. I could stare at them closing all day. Unavoidable: As for installing the slides, cabinets are tight spaces, and it would help to be a Hobbit. Cons: The packaging used to send these was, ahem, minimal. Scarcely thicker than a shoebox. Six of these weigh about 40-50 lbs, so the box was nearly falling apart when it arrived. I would suggest a few extra pieces of cardboard. I mounted these directly to the 'floor' of the cabinet, and as such, I needed the #6 Truss head screws ...which did not come with the kit. A quick trip to the hardware store solved that, but it seems like an oversight. When I ordered a single pair of these slides from another vendor, it came with the truss head screws. It was a small disappointment in an otherwise good experience.

### ⭐⭐⭐⭐⭐ Top-Quality Drawer Slides for a High-End Kitchen
*by M***R on January 28, 2025*

High-End Quality for a Custom Kitchen Got these at the request of my carpenter husband, who is building our kitchen cabinets. If you’re aiming for a high-end kitchen, these are the drawer slides to get—they’re the go-to choice for top cabinet makers. We’ve installed one drawer so far, and it looks fantastic and functions perfectly. My husband says they’re easy to install (though he does this professionally, so beginners might want to consult a YouTube tutorial). Highly recommend Blum for anyone who wants reliable, top-quality hardware with a great reputation. You won’t be disappointed!
