Middle Atlantic Caster Base for DRK 31IN. & 36IN. Deep Enclosure Steel Black Powder - CBS-DRK-31

Middle Atlantic CBS-DRK-31 Caster Base for DRK 31 & 36in. Deep Enclosures

Overview

The Middle Atlantic CBS-DRK-31 is a steel caster base purpose-built for DRK-series 31-inch and 36-inch deep rack enclosures. At 28.88 inches wide and 29.26 inches deep, it matches the DRK enclosure footprint precisely — no shimming, no field fabrication. If you're staging, deploying, or repositioning a fully loaded security rack in a headend room, server closet, or on a warehouse floor, this base gives you a 1,300 lb (589.7 kg) rated mobile platform with a finished, professional appearance. The CBS-DRK-31 (often searched as CBS DRK 31) is designed to be a direct, bolt-up fit rather than a workaround, which matters when the enclosure is already populated with NVRs, patch panels, and power distribution units.

Key Features

• 1,300 lb Weight Capacity: At 589.7 kg rated load, this base handles a fully populated DRK enclosure — servers, NVRs, UPS units, and cabling included — without you having to calculate whether the casters will hold. That rated capacity removes a significant safety variable from dense rack deployments.
• DRK Series Fit: Dimensioned specifically for DRK 31-inch and 36-inch deep enclosures (28.88 in. W × 29.26 in. D). Because it's designed to the same footprint as the enclosure series, you get flush edges and clean alignment rather than the overhang or gaps that come from generic caster platforms.
• 4.03 in. Overall Height: Adding only about four inches to the total rack height keeps the enclosure within standard raised-floor and ceiling-clearance constraints. If vertical space is a concern in your headend, that low-profile lift matters — you're gaining mobility without sacrificing room for additional rack units.
• Black Wrinkle Powder Coat Finish: The same black wrinkle finish used across the Middle Atlantic DRK enclosure line means the base blends visually with the cabinet rather than calling attention to itself. For client-facing equipment rooms or demo suites, that consistency reads as intentional rather than ad hoc.
• Steel Construction: A steel base at this weight capacity (28 lbs product weight) provides rigid support without flex under dynamic loads. When rolling a loaded rack across concrete or tile, a rigid base prevents racking stress on the enclosure's frame and equipment mounting rails.
• Standard Style: The Standard style designation means no non-standard cutouts, no cable-pass-through modifications, and no proprietary attachment hardware — straightforward installation that works within Middle Atlantic's existing DRK mounting ecosystem.

Integration & Compatibility

The CBS-DRK-31 is designed exclusively for the Middle Atlantic DRK enclosure series in 31-inch and 36-inch deep configurations. If you're building out a network video recorder rack or a structured cabling headend on a server rack enclosure, confirm your DRK enclosure's depth before ordering — the CBS-DRK-31 at 29.26 inches deep pairs with DRK cabinets, not the shallower RK or WM series. For planning a complete rack system, review the rack accessories available in the DRK ecosystem to ensure your PDUs, cable managers, and blanking panels all come from the same mounting standard. If you're deploying a high-density surveillance or AV rack and need guidance on load distribution and equipment layout, the racks and enclosures category covers the broader DRK line alongside compatible components.

Frequently Asked Questions

Q: What enclosures is the CBS-DRK-31 compatible with?

A: The CBS-DRK-31 is designed specifically for Middle Atlantic DRK-series enclosures in 31-inch and 36-inch deep configurations. Its dimensions (28.88 in. W × 29.26 in. D) match the DRK enclosure footprint directly.

Q: What is the weight capacity of the CBS-DRK-31?

A: The CBS-DRK-31 is rated for up to 1,300 lbs (589.7 kg), making it suitable for fully populated rack enclosures including NVRs, UPS units, and high-density cabling.

Q: How much height does the CBS-DRK-31 add to my rack?

A: The base stands 4.03 inches (10.2 cm) tall, adding just over four inches to the total enclosure height when installed.

Q: Can the CBS-DRK-31 be used with Middle Atlantic RK or WM series enclosures?

A: No — the CBS-DRK-31 is dimensioned for the DRK series specifically. Using it with other Middle Atlantic enclosure lines is not supported by the manufacturer's specifications.

Q: What is the product weight of the CBS-DRK-31?

A: The CBS-DRK-31 weighs 28 lbs (12.7 kg). Shipping weight is 30 lbs (13.6 kg).

Q: What finish does the CBS-DRK-31 use?

A: It uses a black wrinkle powder coat finish, matching the standard finish used across the Middle Atlantic DRK enclosure series for visual consistency.

The CBS-DRK-31 is the kind of component that gets overlooked during rack planning and then becomes urgent on install day. With a 1,300 lb rated capacity and dimensions matched to the DRK enclosure footprint, it's the right way to mobilize a fully loaded security or AV rack — not a generic caster platform shimmed to fit.

Technical Highlights:

• 1,300 lb Load Rating: At 589.7 kg, this base is sized for worst-case populated DRK enclosures. A fully loaded 42U rack with dual UPS, NVRs, and dense patch cabling can easily exceed 800 lbs — the CBS-DRK-31 has headroom to spare.
• Low 4.03 in. Profile: Adding only 10.2 cm to total rack height is meaningful in rooms with low ceilings or raised-floor height limits. You get full caster mobility without burning vertical space that could otherwise be used for equipment.
• Steel at 28 lbs: The 28 lb product weight (12.7 kg) tells you this is solid steel construction — not sheet metal — which matters when you're rolling 600+ lbs across a concrete data center floor and need the base to resist flex and racking forces on the enclosure frame.

Deployment Considerations:

• Confirm your DRK enclosure's depth designation before ordering — the CBS-DRK-31's 29.26-inch depth is built for 31-inch and 36-inch deep DRK cabinets. Pairing it with a shallower DRK variant will leave the base overhanging the enclosure footprint.
• The 4.03-inch height addition is fixed — there is no adjustable-height version of this base per the available specifications. Factor that into your total rack height calculation before committing to the installation location.

The CBS-DRK-31 is the right call for integrators deploying populated DRK enclosures in headend rooms, equipment closets, or staging environments where periodic repositioning is expected — particularly where a 1,300 lb load rating removes any guesswork about safe rollout under full equipment load.
