Middle Atlantic SNE27F-CN-4542 SNE27W FR,CN RAIL 45UX42D

Product Overview

The Middle Atlantic SNE27F-CN-4542 is a 27-inch wide, 45U open rack frame equipped with cage-nut universal rails, designed for IT and data center environments where standard server and networking equipment with square-hole mounting is the norm. The 42-inch usable depth handles deep 1U and 2U servers, core switches, and enterprise storage systems alongside AV processing gear in a single open-frame enclosure. The cage-nut rail system provides the flexibility to reposition mounting points without dedicated tapped threads, simplifying equipment changes in dynamic infrastructure environments.

Product Description

The SNE27F-CN-4542 combines the structural platform of the SNE27F series with cage-nut universal rails, making it the preferred configuration for IT managers and data center architects who standardize on cage-nut or square-hole rack mounting. The 27-inch interior width exceeds the EIA 19-inch standard, delivering side clearance for structured cabling, airflow channels, and wider chassis that extend beyond conventional rack boundaries. At 45U, this frame provides full-height vertical density for machine rooms, server closets, and dedicated equipment rooms. The 42-inch depth comfortably accommodates deep servers, network appliances, and enterprise storage units without requiring supplemental rear support. Cage-nut rails are the standard in IT and enterprise networking — virtually all server-class hardware from major manufacturers ships with cage-nut compatible mounting hardware. The universal rail design also accommodates M6 cage nuts, offering compatibility across European and North American IT equipment standards. The SNE27F-CN-4542 ships fully assembled and ready for immediate population, reducing on-site setup time. The open-frame construction provides unrestricted airflow on all four sides, supporting passive cooling strategies and reducing dependence on active cooling infrastructure. Full compatibility with Middle Atlantic's accessory ecosystem — PDU brackets, horizontal cable managers, lacing bars, and vented blanks — ensures this frame scales with growing infrastructure demands. Available through authorized partners including Creation Networks.

Frequently Asked Questions

What is the difference between cage-nut rails and 10-32 tapped rails?

Cage-nut rails have square holes that accept removable cage nuts, allowing you to install and reposition mounting points anywhere in the rail. Tapped 10-32 rails have pre-threaded holes at fixed positions. Cage-nut rails are standard for enterprise server and networking equipment; 10-32 tapped rails are standard for professional AV equipment.

Can I use both cage nuts and tapped screws in the same rack?

Cage-nut rails accept only cage nuts. If you need to mix AV gear (10-32) and IT gear (cage-nut) in the same rack, the SNE27F-4542 with 10-32 tapped rails may be more appropriate, or you can use adapter cage nuts designed for 10-32 threading.

Is the SNE27F-CN-4542 compatible with standard 19-inch server equipment?

Yes. The rail spacing on SNE Series frames conforms to the EIA-310 19-inch rack standard. The 27-inch interior width provides additional side clearance but does not affect compatibility with standard 19-inch rack-mount equipment.

Where can I purchase the SNE27F-CN-4542?

The SNE27F-CN-4542 is available through Creation Networks, an authorized Middle Atlantic reseller.
