GRS Series 3-Piece
Trunk and
Distribution
Connectors
GRS series 3-piece trunk and
distribution connectors are
used in low power RF, video,
data signals and powered
broadband systems. Chassis
mounting connectors are used
in 5/8-24 equipment entry.
• Independent seizing of the
center conductor permits
installers to physically verify
the center conductor has been
seized prior to tightening the
back nut
• Placement of the integral
mandrel of the connector in the
main nut provides a full view of
the center conductor's entrance
into the seizing mechanism and
requires minimal pull back for
ease of installation
• Domed insulator at the KS
interface prevents moisture
from collecting between the
contact pin and connector body,
reducing the possibility of
corrosion
• The GRS connectors have a
center conductor cutting guide
• Reusable
