Middle Atlantic 28W/46SP SR Perf Frnt DR - LVFD28-46

Middle Atlantic LVFD28-46 46U Vented Front Door for SR28 Series Racks

Overview

The Middle Atlantic LVFD28-46 is a 46U vented front door engineered specifically for the SR28 series rack enclosure line. At 81.4 inches tall and 25.4 inches wide, this door replaces or adds a front panel to a 28-inch-wide, 46-rack-unit enclosure — providing physical access control and thermal management in a single component. If you're running active networking gear, dense patch fields, or security NVRs in a closed cabinet and dealing with recirculated hot air, the 64% open vent area is the spec that matters most here.

The LVFD28-46 (often searched as LVFD28 46) ships at 36 lbs and installs directly onto SR28 series cabinets without field modification. The textured black powder coat finish holds up to the scuffs and contact that come with a working equipment room or IDF closet — this isn't a cosmetic panel, it's a working door rated for operational environments.

Key Features

• 64% Vent Open Area: More than half the door face is open — this isn't a token perforation pattern. In a fully loaded 46U rack running switches, recorders, and servers, restricted airflow is the single most common cause of thermal throttling and premature component failure. A 64% open area means the door itself is not the airflow bottleneck in your chassis cooling stack.
• 46 RU / 81.4-Inch Height: Full-height coverage for a 46U SR28 enclosure. No exposed rack rail gaps, no mismatched panel heights. At 81.4 inches (206.8 cm), the door aligns flush with standard 46U SR28 cabinet dimensions — critical in shared equipment rooms where aesthetics and door-swing clearance both matter.
• 25.4-Inch Width for SR28 Compatibility: The 28-inch-wide SR28 series is a common footprint in mid-market security and AV installations. This door is precision-matched to that series at 25.4 inches (64.5 cm) width — no shimming, no custom hardware, drop-in replacement or first-install fit.
• 1.39-Inch Depth Profile: At 3.5 cm of depth, the door adds minimal projection in front of the rack face. In equipment rooms where multiple cabinets are deployed in rows and aisle spacing is tight, a thin door profile keeps you within IDF clearance guidelines without sacrificing the ventilation benefit.
• Textured Black Powder Coat Finish: Powder coat is more durable than painted steel for rack hardware — it resists chipping from tool contact and door closure impact that's routine in working equipment rooms. Textured black also hides minor surface wear better than smooth finishes over a multi-year deployment lifecycle.
• 36 lb Shipping Weight: The door ships at 36 lbs (16.3 kg), which is within one-person installation range with the right lift assist. Worth planning for if you're deploying in a rack room with restricted access or installing at height on a raised-floor environment.

Integration and Compatibility

The LVFD28-46 is designed for the Middle Atlantic SR28 series rack enclosures. Verify your installed cabinet is an SR28-46U configuration before ordering — the door hinge and latch geometry is keyed to that series. It will not retrofit to non-SR28 enclosures without modification, and Middle Atlantic does not publish a cross-series compatibility path for front doors.

For installations combining this door with active cooling, pair it with a rear exhaust panel or top-mount fan tray to complete a front-to-back airflow path. The rack accessories category includes compatible blanking panels, cable managers, and fan units that work alongside this door in the SR28 line. For new builds, review your network rack enclosure selection alongside this door to confirm the full 46U SR28 cabinet configuration before procurement.

If your deployment involves IP security equipment — NVRs, PoE switches, video management servers — proper rack ventilation is directly tied to system uptime. Consult the rack planning guide for airflow and power density calculations before finalizing the enclosure build.

Frequently Asked Questions

Q: Is the LVFD28-46 compatible with SR28 cabinets of different rack unit counts?

A: No. The LVFD28-46 is sized specifically for 46U SR28 enclosures — 81.4 inches tall and 25.4 inches wide. It will not fit SR28 cabinets in other rack unit configurations (e.g., 36U or 52U). Always match the door model to the exact RU count of your installed cabinet.

Q: What is the vent open area percentage on the LVFD28-46?

A: The LVFD28-46 has a 64% vent open area. This is the portion of the door face that is perforated or open, allowing airflow through the front of the enclosure. A higher open area percentage reduces impedance to front-to-back cooling airflow in actively ventilated racks.

Q: Does the LVFD28-46 include a lock or latch?

A: The available evidence does not confirm lock or latch hardware specifics. Consult the Middle Atlantic SR28 door accessories documentation or contact a pre-sales specialist to confirm locking options for this door model.

Q: What is the finish on the LVFD28-46?

A: Textured black powder coat. This finish is applied over the steel door construction and provides resistance to chipping and surface wear typical in working equipment room environments.

Q: What does the LVFD28-46 weigh, and can one person install it?

A: The shipping weight is 36 lbs (16.3 kg). Installation at height or in confined rack rooms may require two people or a lift assist. The door itself is a direct-fit replacement for SR28 46U enclosures with no field modification required.

Q: What series does the LVFD28-46 belong to?

A: The LVFD28-46 is part of the Middle Atlantic LVFD vented front door line and is specifically matched to the SR28 base series of rack enclosures. The
