Middle Atlantic SNE27H-4236-A1 – 27" 42U 36" Hybrid Network Enclosure

Product Overview

The Middle Atlantic SNE27H-4236-A1 is a 27.6-inch wide, 42-rack-unit, 36-inch deep Hybrid Slim Network Enclosure configured with a 660 CFM proportional thermostatic fan top for active top-exhaust thermal management. Sitting at the mid-width tier of the SNE Hybrid series, this enclosure offers more interior horizontal clearance than standard 24-inch models while remaining narrower than 30-inch enclosures. The SNE27H-4236-A1 is designed for commercial AV integrators deploying mixed analog and digital equipment racks in boardrooms, conference rooms, and network equipment rooms where the A1 top-exhaust fan configuration is the preferred cooling approach. It is UL listed and seismic certified for use on regulated commercial and government projects.

Product Description

The SNE27H-4236-A1 combines the 27.6-inch wide SNE enclosure body with the A1 active cooling configuration — a proportional thermostatic fan top delivering 660 CFM of top-exhaust ventilation. Proportional thermostatic control adjusts fan speed relative to measured internal temperature, operating quietly at lower speeds during reduced heat-load periods and ramping up as thermal conditions require.

The Hybrid rail system provides two pairs of adjustable 10-32 tapped rack rails for standard AV equipment, complemented by a 4-space cage-nut adaptor pair for IT devices requiring 6mm cage-nut mounting. Lever Lock compatibility is included with two 10-inch wide Lever Lock mounting plates for tool-free integration of power distribution, cable management, and small AV devices. The 70% open-area front door enables front-inlet airflow, while the solid top integrates the fan assembly for top-exhaust. Split flush-mount locking side panels provide security and a finished enclosure appearance. Four casters for installation mobility and four leveling feet for stable final placement are included. A 6-inch wide vertical wire grid lace panel provides structured cable management. The SNE27H-4236-A1 is available from Creation Networks at creationnetworks.net.

Frequently Asked Questions

Q: What is the difference between the SNE27H-4236-A1 and the SNE27H-4236-A2?

A: The A1 uses a fan top delivering 660 CFM of top-exhaust ventilation with proportional thermostatic control. The A2 uses a split fan rear door with eight 6-inch fans delivering 1,760 CFM of rear-exhaust airflow. The A1 is preferred when top exhaust suits the installation; the A2 provides significantly higher airflow for heat-dense equipment.

Q: Why choose the 27.6" width over the 24" models?

A: The 27.6-inch width provides additional horizontal interior clearance for wider AV processors, equipment with wider chassis footprints, or installations where lateral cable routing requires additional space inside the enclosure.

Q: Does the proportional thermostatic controller reduce fan noise?

A: Yes. The proportional thermostatic controller runs the fan at lower speeds when heat loads are reduced, which decreases noise output. The fan ramps up only when internal temperatures require higher airflow.

Q: What rail mounting standards are supported?

A: Two pairs of 10-32 tapped adjustable rack rails for standard AV and analog equipment, plus a 4-space cage-nut adaptor pair for IT equipment using 6mm cage-nut hardware.

Q: Does this enclosure carry seismic certification?

A: Yes. The SNE27H-4236-A1 is UL listed and seismic certified for regulated commercial and government AV installations.

Q: What Lever Lock accessories are compatible?

A: All Middle Atlantic Lever Lock vertical 21-inch accessories are compatible. Two 10-inch wide Lever Lock mounting plates are included for tool-free accessory installation.

Q: Where can I purchase the SNE27H-4236-A1?

A: Available from Creation Networks at creationnetworks.net.
