Lowell RRB Rail Recessing Brackets For Rack Rail Mounting | 3U

The Lowell RRB Series rail recessing brackets are designed for AV integrators and rack system installers who need to set equipment back from the front face of a rack rail. By positioning gear 4 inches behind the rail, these brackets create clearance for cable management, ventilation, or flush-mounting requirements common in permanent installation environments such as equipment rooms, control suites, and rack-mounted speaker systems.

Constructed from 16-gauge steel with a smooth black powder epoxy finish, the RRB Series is built to handle the structural demands of professional rack builds without adding unnecessary complexity. The brackets fit over the rack's existing tapped mounting rails rather than replacing them, making them compatible with standard tapped rack infrastructure without requiring modifications. Each pair ships with hardware included, reducing installation time on the job site.

Available in 2U, 3U, and 4U configurations, the RRB Series covers a range of rack unit requirements in a single product family. This flexibility makes the line practical for integrators managing multiple rack builds with varying equipment heights, eliminating the need to source recessing solutions from multiple vendors.
