The SOA-5U swing-out adapter (Figure1) is a wallmounted accessory for Enginuity’s Model WR-5UI2 wall
rack. The SOA-5U provides a hinge mechanism that
allows the WR-5UI2 to swing out for access to the rear of
equipment mounted in the rack. The adapter’s flexible
cable guide and ground strap ensure that cabling remains
kink-free while using the swing-out feature.

Enginuity’s Model WR-5UI2 wall rack supports any
combination of standard 19-inch rack-based equipment,
up to a total of five rack units high. When equipment in
the WR-5UI2 requires rear access to connectors, plugins, etc., the SOA-5U swing-out adapter enables the wall
rack to pivot up to 90°.
The symmetrical design of the SOA-5U allows it to be
mounted in a swing-left or swing-right position, providing
flexibility when choosing an installation location. The
swing-out adapter adds minimal depth to the wall rack

assembly. The SOA-5U gets mounted to the wall before
the WR-5UI2 is mounted onto the SOA-5U. Figure 2
illustrates the complete assembly. Equipment cables and
ground wiring are groomed and secured by the cable
management features of the SOA-5U and WR-5UI2.
The SOA-5U is constructed of heavy-gauge steel for
service provider applications. Its integrated hardware
fasteners provide a precise fit to the WR-5UI2. The
product’s frame, hinge mechanism, and cable guide are
preassembled and ready for wall mounting. Figure 3
highlights the main features of the SOA-5U.
