3.0 Tool Description
3.1 Main Splicing Rig Components
The 4041 Splicing Head is used with a support
rig for:
• Initial termination of conductors in the
modules.
• Making connections with preterminated
modules.

conductors in their proper locations during the
splicing procedure. The splice head will hold
the following module combinations:
• 1 Super-Mini and 1 Super Mate
• 2 Super Mates
• 3 Super Mates
