RB Hub

Equipment with an RB suffix, meaning Rainproof Type 3R construction,
uses the bolt-on hubs listed below. RB devices will accept 0.75 in. (19 mm)
through 2.50 in. (64 mm) bolt-on hubs without the use of reducers. Offcenter conduit thread openings and elongated mounting holes provide quick
and easy adjustment to eliminate costly conduit offsets and bends. Hubs are
suitable for use with conduit having ANSI standard taper pipe thread.
