METABOX gives you a steel drawer system built for everyday use. At 100 pounds static load capacity, these slides handle real-world kitchen and shop storage with the reliability contractors expect from Blum hardware.
The system comes in three distinct heights that actually make sense for different storage needs. The standard 3-3/8 inch height (320M) works for everyday drawers. Step up to 4-5/8 inches (320K) for medium storage, or go with the 5-7/8 to 6 inch high version (320H) when you need maximum drawer depth. That flexibility beats having to stock multiple slide systems for different projects.
Why METABOX Works for Standard Projects
The epoxy-coated alloy steel construction holds up better than bare metal slides that rust in humid environments. Synthetic rollers on tempered steel axles deliver smooth operation without the metal-on-metal grinding you get with basic slides. The 3/4 extension doesn’t give you full drawer access like some other slides, but it’s sufficient for most residential applications.
What really matters: 55-75 pounds dynamic load per pair handles everything from dinnerware to cast iron cookware. The 22-inch (550mm) standard length fits most base cabinets without modification. And the 1/2 inch side clearance requirement works with standard cabinet construction.
Captive right-hand profiles mean the slides stay aligned during installation. No fighting with pieces that want to separate while you’re trying to mount them. Small detail, but it matters when you’re installing a kitchen’s worth of drawers.
Real-World Performance
Ferguson Home’s store shows 4.7 stars across 42,000+ reviews, though that’s for the retailer, not specifically METABOX. More relevant: CabinetParts.com shows 4.8 stars from 28 reviews on the 6-inch height version. Lowe’s rates them 4.2 stars from 10 reviews. Not spectacular numbers, but solid for standard hardware.
Compared to Blum’s 430 series, METABOX is positioned as the standard option while the 430 offers full extension. You’re trading drawer access for other benefits. METABOX also gets mentioned alongside Blum’s TANDEM slides, their hidden slide system. Different leagues entirely — TANDEM disappears completely while METABOX remains visible as a traditional side-mount.
Skip METABOX if you need soft-close functionality. These don’t include BLUMOTION as standard. Also skip them for high-end kitchens where clients expect full drawer extension. But for rental properties, standard remodels, and shop storage? METABOX delivers Blum quality for practical applications.

You get solid, functional hardware that works.
Frequently Asked Questions
Q: What’s the weight capacity of Blum METABOX drawer slides?
Blum METABOX slides handle 100 pounds static load and 55-75 pounds dynamic load per pair. That’s enough for standard kitchen storage including heavy cookware and dishes, though not as robust as premium drawer systems.
Q: What drawer heights are available in the METABOX system?
METABOX comes in three heights: 3-3/8 inches (320M model) for standard drawers, 4-5/8 inches (320K) for medium storage, and 5-7/8 to 6 inches (320H) for deep drawers. Each height uses the same 22-inch slide length and mounting system.
Q: How far do METABOX slides extend?
Standard METABOX slides provide 3/4 extension, meaning you can’t access the back quarter of the drawer. Blum’s 430 series offers full extension if you need complete drawer access.
Q: Do METABOX slides include soft-close?

Q: What’s the side clearance requirement for METABOX installation?
METABOX slides require 1/2 inch side clearance for proper installation. The slides feature captive right-hand profiles that keep components aligned during mounting.
Q: How does METABOX compare to Blum’s other drawer systems?
METABOX is Blum’s standard steel drawer system with visible side-mount slides and 3/4 extension. Their TANDEM system offers hidden slides for different applications, while the 430 series provides full extension functionality.
