Middle Atlantic SNE27D-4242-P1 – 42U Security Network Enclosure, 27W x 42D

Product Overview

The Middle Atlantic SNE27D-4242-P1 is a fully configured 42U security network enclosure built for digital, IP-based security systems with high-density cabling, network equipment, and servers. Its 27-inch width and 42-inch overall depth give installers extra room for deep network hardware and structured cabling. The SNE Series Digital configuration ships with passive front-to-rear ventilation, locking panels, and rackrail pre-installed, so commercial deployment teams can rack equipment on day one. It is a strong fit for IT rooms, security head-ends, and data center installations across corporate and government facilities.

Product Description

This SNE Series Digital enclosure arrives configured for IP-based security and network infrastructure rather than as a bare frame. The 70% open area vented front door and 70% open area split rear door support passive front-to-rear cooling for network switches, recorders, and servers without adding fan noise or powered ventilation. A solid top with brush cable pass-through manages overhead cable entry while keeping dust intrusion down.

Inside, two pairs of adjustable cage-nut rackrail accept standard 19-inch equipment, and Middle Atlantic includes 100 6mm cage nuts and rack screws in the box. The enclosure is Lever Lock compatible, accepting all 21-inch vertical Lever Lock accessories for tool-free mounting of small devices such as encoders, power supplies, and access control system components — a meaningful labor saver during security system integration. A pair of split, flush-mount locking side panels restricts physical access to the equipment, which matters for surveillance and access control installations.

The enclosure is UL/ETL listed and seismic certified, supporting specification in government and institutional projects with code requirements. Four leveling feet and four casters are included, so the rack can be loaded, rolled into position, and leveled in place. For matching racks, power distribution, and accessories, browse the Middle Atlantic collection at Creation Networks.
