General Information

GAI-Tronics Page/Party® systems are industrial
communication systems designed to be both flexible and
durable to survive challenging industrial environments. The
9000 Series consists of a wide array of products and
configuration options that enable it to meet diverse
applications. The 9000 Series design incorporates
technologically-advanced materials to endure harsh
environments.

The Model 9974 Junction Box is packaged in glass­reinforced polyester with the housing composed of two
modular subassemblies: the front panel and the rear
enclosure. This modular design allows the front panel to be
detached from the rear enclosure to simplify installation.

Mounting

1. Remove the front panel by loosening the four captive screws and swinging the panel open to the left.

Pull the hinges out of the holes in the rear enclosure to expose all four mounting holes.

2. Determine which of the four available conduit locations is to be used. Drill spots have been provided

for use with a chassis punch or hole saw. We recommend using 1.25-inch conduit hub assemblies
because this size hub will make the proper contact with the supplied grounding plate. In using any
conduit hub assembly other than the recommended size, it is the installer’s responsibility to provide
the proper earth ground bonding. Hubs must be connected to the conduit before being connected to
the enclosure.

Approved conduit entry hub assemblies:

 GAI-Tronics 14611-004 (1¼-inch)
 Myers ST-4 (1¼-inch)
