Middle Atlantic ERK 35SP Vent.reardr Opti - ERK-VRD-35

Middle Atlantic ERK-VRD-35 35U Vented Rear Door

Overview

The ERK-VRD-35 is a 35U vented rear door designed specifically for Middle Atlantic ERK series racks. At 64% open area, it allows substantial passive or forced-air ventilation through the rear of the enclosure — the right choice when you're housing active network equipment, NVRs, or amplifiers that generate consistent heat load and need rear exhaust clearance. At 1.22 inches deep and 19.44 inches wide, it fits flush to the ERK frame without adding meaningful footprint. For installations where you're building out a rack enclosure with thermally dense equipment, replacing a solid rear panel with the ERK-VRD-35 is one of the fastest ways to reduce ambient temperature inside the cabinet without adding a dedicated fan tray.

Compatibility

The ERK-VRD-35 is purpose-built for the Middle Atlantic ERK rack series — specifically 35U ERK enclosures. It is not a universal fit; the mounting geometry is ERK-specific. Verify your rack is an ERK-series unit before ordering. The 35U designation must match your enclosure's rack unit count exactly — a 35U door will not correctly align on a 27U or 42U ERK frame. If you're configuring a full enclosure build, pair this with compatible rack accessories such as side panels, blanking panels, or fan modules from the ERK accessory line. For thermal planning across multi-rack deployments, review a rack cooling and airflow guide to confirm whether passive venting at 64% open area is sufficient or whether active fan modules are required for your heat load.

Installation Notes

Shipping weight is 30 lbs (13.6 kg) — plan for two-person handling when mounting. The door dimensions are 60.31 in H × 19.44 in W × 1.22 in D; confirm rear clearance in your installation space before mounting, particularly in tight IDF closets or wall-recessed rack bays where rear access is limited.
