Westek introduces the TC-TLCP Terminal Lug Cap Puller which saves time and money while protecting your field employees from unnecessary injuries that might otherwise occur when removing terminal lug caps with sharp or improper tools.
What makes more sense than using
the right tool for the job?
Consider the TLCP's Many Features:
The PTL-6 adapter plug allows use of standard PBX/ ACD headset with modular telephones. PBX headsets equipped with the standard PJ327 dual brass plug may now plug into telephone consoles with 4x4 or 4x6 modular jack
The head of the tool is designed to slide over
the terminal lug cap, securing it for fast and
easy removal
Once removed, the cap remains in the tool for
reinstallation Specially designed ribs encircle
the handle, providing a positive grip in dry or
wet conditions. The compact handle fits all
hand sizes and rests against the palm of the
hand for increased force during lug cap
installation. A tough, non-conductive plastic
body assures a long, useful life even under
the most abusive conditions.
