Installation Procedure

The instructions provided by the manufacturer of the hardline connector contain

important information, but may omit details that help ensure consistently reliable

results.
As a case in point, consider the following instructions and reference drawing that

accompany the Gilbert GRS pin-type connector for CommScope .500 diameter PIII

hardline cable:

Install Back Nut onto cable. Install Main Nut onto cable to check cable trim coring dimensions.... Verify the

connector pin length and, if necessary, trim the connector pin to the appropriate length for the equipment being

used. Install the connector Body into the housing and tighten to housing manufacturer's specification. Slide the

Main Nut onto the prepared end of the cable making certain that the integral sleeve is fully inserted into the cable.

Bring the Main Nut and cable to the Body. Hand tighten Main Nut to Body continually keeping pressure on cable

towards body so that the center conductor will be properly seized. Then, using two wrenches, one wrench to hold

the Body from rotation, continue tightening Main Nut to Body until a firm stop is reached, re-verify that the

integral sleeve is fully inserted into cable. Tighten Back Nut by hand; then, using two wrenches, one of the Main

Nut, complete installation by tightening Back Nut firmly to secure the cable (approximately 35 ft.lbs. [50 Nm];

approximately 50 ft.lbs. [70 Nm] for .840 and larger cable sizes). Secure center conductor in equipment housing

with seizing screw provided by equipment manufacturer 1. Slide heat shrink tubing over connector against port

housing of equipment. Shrink in accordance with manufacturer's recommendation.
