Strong SR-CS-RACK-21U Contractor Rack 21U 18 Inch

Product Description

The STRONG SR-CS-RACK-21U is a 21U contractor-grade rack enclosure designed for ceiling-mount installations in low-voltage structured cabling and AV distribution applications. With an 18-inch depth, this rack provides sufficient clearance for patch panels, switches, media converters, and other rack-mount equipment commonly deployed in commercial and residential integration projects. The open-frame or enclosed rack format accommodates standard 19-inch rack-mount gear and is intended for installation by low-voltage contractors, AV integrators, and structured cabling technicians.

This rack is suited for ceiling-mount deployments where floor or wall space is limited, such as drop-ceiling plenum spaces, utility rooms, and overhead distribution points in commercial buildings, hospitality environments, and multi-unit residential installations. The 21U height offers meaningful rack space for consolidation points or small equipment rooms without requiring a full-size enclosure. Installation teams working on distributed AV, security, or network infrastructure will find this format appropriate for overhead equipment runs.

Key Features

Compatibility

Designed as an OEM-style contractor rack for ceiling-mount structured cabling and AV equipment installations accepting standard 19-inch rack-mount components.

Installation Notes

Installation should be performed by a qualified low-voltage contractor or AV integration technician familiar with ceiling structural requirements and local building codes. De-energize all circuits in the work area before mounting or terminating any equipment in the rack. Verify that the ceiling structure can support the combined weight of the rack and all installed equipment before fastening. Follow applicable codes including NFPA 70 (NEC) for any powered equipment installed within the enclosure.
