Middle Atlantic 4SP Textured Drawer - TD4

Middle Atlantic TD4 4-Space Rack Drawer — Textured Steel

Overview

The Middle Atlantic TD4 is a 4-rack-unit steel storage drawer built for 19-inch equipment racks in security operations centers, AV head-end rooms, and IT closets. At a rated UL-verified 50 lb load capacity and a 15.45-inch interior depth, the TD4 handles everything from spare cabling and tools to installed surveillance recording media and portable gear — without flexing or shifting in the rack. If you're running a multi-camera NVR installation and need organized, lockable access to peripheral hardware at the rack, this is the drawer tier that handles real weight on a production installation. The TD4 occupies exactly 4 RU, so plan your rack accessories and equipment layout accordingly before ordering.

Key Features

• 50 lb UL-Listed Load Capacity: The UL-verified 50 lb (22.7 kg) rating isn't a marketing ceiling — it's a tested, listed value. That means hard drives, NVR appliances set on a pull-out shelf, or a full complement of cabling reels won't deflect the drawer floor or stress the slides. For security integrators storing surveillance drives or spare hardware in the rack, this load rating matters during service calls.
• 15.45-Inch Interior Depth: At 15.45 in (39.2 cm), the drawer accommodates most compact NVR form factors, UPS battery modules, and organized cable trays end-to-end without overhang. Measure your target gear against this depth before spec'ing — anything deeper than roughly 14 inches needs to sit flat, not propped.
• 4-RU Height (7 inches): The 7-inch (17.8 cm) opening gives you enough vertical clearance for stacked hard drive trays, portable test equipment, or flat storage bins. In a 42U rack, committing 4U to a drawer is meaningful — confirm your rack layout allows the space before ordering.
• 19-Inch Standard Rack Width: At exactly 19 in (48.3 cm), the TD4 mounts flush in any standard EIA-310 19-inch rack using the two provided mounting points. No adapter rails needed for standard rack posts.
• Textured Black Powder Coat Finish: The textured black powder coat on the steel body resists fingerprints and minor abrasion better than gloss finishes — important in high-touch environments like NOC racks or operations consoles where the drawer gets pulled and pushed repeatedly during service rotations.
• Steel Construction: All-steel body means the drawer maintains its geometry under load and doesn't rack or bow over years of use, unlike polymer alternatives that can warp under sustained weight or in warm equipment rooms.
• Two Rack-Mount Points: The dual mounting-point design keeps installation straightforward with standard rack hardware — no specialty fasteners or cage nut configurations required beyond what's already in your rack inventory.
• No Lock Configuration: The TD4 ships without a lock. For deployments where physical access control to drawer contents is required — spare credentials, key fobs, or licensed media — plan to pair it with a separate rack-mount lock drawer or a lockable rack enclosure from the Middle Atlantic rack and enclosure line.

Integration and Compatibility

The TD4 integrates into any standard EIA-310 19-inch rack rail system — open-frame, enclosed, or wall-mount configurations with sufficient depth. At 15.45 inches of drawer depth, verify your rack's interior depth provides adequate clearance with the drawer fully extended. The drawer is part of Middle Atlantic's D-TD heavy duty drawer series and pairs naturally with network rack cabinets and open-frame racks used in security head-end rooms. For larger installations requiring additional storage across multiple rack positions, consider complementary rack shelf options for non-drawer fixed storage needs. The steel construction and standard rail mounting make it forward-compatible with any future rack system that conforms to 19-inch EIA standards. No power or data connections are required — pure passive mechanical hardware.

Frequently Asked Questions

Q: What is the maximum load the TD4 can hold?

A: The TD4 carries a UL-listed load capacity of 50 lbs (22.7 kg). This is a verified, tested rating — not an estimated maximum.

Q: Does the TD4 include a lock?

A: No. The TD4 does not include a lock. If physical access control to the drawer contents is required, plan for a separate locking solution at the rack enclosure level.

Q: Will the TD4 fit in a standard 19-inch rack?

A: Yes. The TD4 is 19 inches wide and uses two standard rack-mount points, making it compatible with any EIA-310 19-inch rack system. Verify your rack has at least 4 RU of open space and sufficient interior depth (the drawer extends 15.45 inches).

Q: How many rack units does the TD4 occupy?

A: The TD4 occupies 4 rack units (4 RU), with a 7-inch overall height.

Q: What is the drawer depth — how much interior space is available?

A: The TD4 provides 15.45 inches (39.2 cm) of depth. Measure your target equipment against this dimension before ordering to confirm fit with the drawer fully extended.

Q: What finish does the TD4 use?

A: Textured black powder coat over steel — a durable, abrasion-resistant finish suited for high-touch rack environments.

The TD4 is one of those components that sounds boring until you're on-site during a service call and need quick, organized access to spare drives or cabling in a production rack. The 50 lb UL-listed load rating is the spec that separates this from lighter-duty alternatives — you can actually store populated hard drive trays or compact recording appliances in this drawer without worrying about slide failure over time.

Technical Highlights:

• 50 lb UL Load Rating: Most generic rack drawers carry nominal load claims without third-party verification. The TD4's UL listing means the 50 lb capacity is tested and traceable — relevant when you're stacking surveillance HDDs or leaving portable test equipment in the rack between visits.
• 15.45-Inch Depth: Fits the majority of 2.5-inch and 3.5-inch drive caddies, compact media converters, and tool kits without overhang. For anything approaching 15 inches long, confirm the measurement — there's no margin to spare.
• Steel Construction + Textured Powder Coat: The all-steel body at 14.91 lbs product weight means it won't flex under load the way sheet-aluminum drawers can. The textured finish handles routine contact in a working rack environment without showing wear the way gloss finishes do.

Deployment Considerations:

• Plan your rack U-count carefully — 4 RU is a meaningful commitment in a fully loaded 12U or 16U wall-mount enclosure. If storage is secondary to equipment density, consider whether a 2RU shelf serves the use case better.
• The TD4 ships without a lock. In any deployment where the rack is in a semi-public or shared space (server rooms with broad access, retail back-office locations), physical security for drawer contents has to be handled at the enclosure level, not the drawer.

The TD4 fits best in security head-end rooms and NOC racks where integrators need a reliable, heavy-duty pull-out storage point for surveillance media, spare hardware, or field service tools — specifically where gear weight rules out lighter-duty options.
