TANDEM is Blum's concealed runner system designed specifically for wooden drawer boxes. These steel runners mount inside your cabinet, completely hidden from view, and provide what Blum describes as a "feather-light glide" when you open and close your drawers.

Where It Fits

This system works with wooden drawer boxes between 11mm and 16mm thick. The concealed mounting means you won't see any hardware when your drawers are closed, making it particularly suitable for traditional or contemporary kitchens where you want clean lines without visible mechanical elements.

How It Works

The runners mount to the inside walls of your cabinet and connect to your wooden drawer box through either a locking device or hook and peg system. When installed, your drawer extends fully, giving you complete access to everything stored inside. The system includes integrated height adjustment up to 2mm, and on full extension versions, tilt adjustment to help align your drawer front perfectly with your cabinet.

Why It Matters

The smooth operation means you can open drawers with minimal effort, even when they're fully loaded. Full extension is particularly valuable in kitchen storage because you can reach items at the very back of deep drawers without having to remove everything in front first. The concealed design maintains the visual focus on your kitchen's design rather than its hardware.

Design Consideration

TANDEM works well when you want the mechanical elements completely hidden and you're working with wooden drawer construction. The system requires precise installation to achieve optimal performance. If you prefer the flexibility of metal drawer boxes or need specific load ratings for very heavy storage, other systems might be more appropriate.

Build Quality

The runners are made from zinc-plated steel for durability and smooth operation. Blum provides a lifetime guarantee on the mechanism, reflecting their confidence in the long-term performance. The adjustment features are built into the hardware rather than requiring separate components.

Closing Guidance

Consider TANDEM if you're planning wooden drawer boxes and want completely concealed hardware with smooth, reliable operation. The system works particularly well in kitchens where the drawer construction and cabinet joinery are being carefully coordinated from the start of the design process.
