The RDAB2U31 is a 2U rack depth adapter bracket set from the RDAB Series, used to support deep equipment in 2-post rack systems. It is aimed at IT and network integrators, telecom technicians and facilities teams who need to mount servers, UPS systems and deep chassis in a 2-post relay rack where no rear posts are available for support.
Each set is built from 14-gauge mild steel with a black smooth powder coat finish and carries a 400 lb capacity. The brackets provide both mounting rails and formed angle supports, so rackmount and non-rackmount equipment can be carried. Brackets can be fastened to the front and/or rear rack rails to maximize load capacity and installation flexibility, and they are compatible with 19-inch, 23-inch and 24-inch EIA rack systems.
The RDAB2U31 measures 3.50 in (89 mm) high and 1.57 in (40 mm) wide per bracket, with a 14.00 in (356 mm) depth per bracket. Mounting dimensions are 3.50 in (89 mm) high by 19.00 in (483 mm) wide, giving a total mounting depth of 31.00 in (787 mm) including a standard rack. The brackets occupy 2 rack units. Mounting holes are 0.250 x 0.375 in obround (6 places per bracket) with tapped 10-32 provisions.
The set is sold in pairs of 2 right and 2 left brackets and ships with 10-32 x 0.625 in screws and installation instructions. By centering equipment within the rack, RDAB2U31 distributes weight more evenly across the rack structure, reducing sag and stress on the mounting rails. The part is TAA compliant, USMCA compliant, RoHS and REACH compliant, and made in Canada.
Ideal For
- Supporting deep servers, UPS systems and chassis in 2-post racks
- Converting front-mounted equipment to center-supported installations
- Data center, IT, network and telecom rack installations
- Industrial and control system rack deployments
- Mounting deep equipment without requiring a full 4-post rack
