Raintight—NEMA Type 3R Wireway
Application
Raintight—NEMA Type 3R Wireway is designed to protect electrical wiring in outdoor installations against rain, sleet, and snow or indoors against dripping water. All sections and fittings are completely open on one side so wires and cables can be laid in along an entire wireway run. No pulling through of wires or cables is required with this design.
Raintight Lay-in—NEMA Type 3R Wireway
A complete selection of sections and fittings is available in three sizes:
| Inches | Millimeters |
|---|---|
| 4.00 x 4.00 | 102 x 102 |
| 6.00 x 6.00 | 152 x 152 |
| 8.00 x 8.00 | 203 x 203 |
Construction
Raintight NEMA —Type 3R Wireway construction consists of:
-
16 gauge galvanized steel straight sections in sizes:
-
4.00 x 4.00 in. (102 x 102 mm)
-
6.00 x 6.00 in. (152 x 152 mm)
-
-
14 gauge galvanized steel straight sections in size:
-
8.00 x 8.00 in. (203 x 203 mm)
-
-
Open top assembly protection for wire and cable insulation that might otherwise be damaged in a pull through wiring system
-
Self-connecting system with minimum usage of fasteners
-
Removable covers held firmly closed with quick-release latches to maintain rain-tightness throughout
-
Quick-release cover latches permit immediate access to wireway interior

Wireway Components
The Raintight—NEMA Type 3R Wireway Sample Layout illustrates how most of the Raintight—NEMA Type 3R Wireway sections and fittings could be used in an actual wireway run. Many different sections and fittings can be combined into any configuration needed.
Raintight—NEMA Type 3R Wireway Sample Layout
Straight Section
Available in lengths from 1 ft. (30 cm) to 10 ft. (305 cm).
90° Flush Tee
Use wherever flush mounting against a vertical surface is required.
30° Sweep Elbow
When a large radius is needed, use this sweep elbow.
90° Elbow-Tee-Cross
Use when there are four branches. It can be used as a 90° Elbow or a 90° Flush Tee by adding Closure Plates.
90° Elbow
Used whenever a right-angle installation is needed.
Panel Adapter
Allows the wireway to be securely connected to an enclosure.
Closing Plate
Closes the end of a wireway section or run.
Reducer
Used to reduce to a smaller wireway size.
Connector
Used to rigidly join fittings to straight sections.
Drop Hanger
Used to support a wireway run.
Bracket Hanger
Used to support a wireway run.
Wall Hanger
Used to support a wireway run.
