The TE Connectivity 216003-2 is a stuffer cap designed for use with RJ11 jacks. It fits over the jack's termination area after wiring, acting as a strain-relief backfill and dust cover for the IDC or solder terminations on the rear of the jack. This keeps the exposed contacts from snagging on other wiring or shorting against the enclosure panel during installation or service.

Frequently asked questions
Is the 216003-2 compatible with all RJ11 jacks?
No. The 216003-2 is designed for use with TE Connectivity RJ11 jacks specifically. Its internal profile matches the rear of TE's own jack bodies; jacks from other manufacturers may have different rear housing dimensions that prevent the cap from seating properly.
What is the 216003-2 stuffer cap used for?
The 216003-2 is a stuffer cap that fits over the rear termination area of an RJ11 jack. It provides strain relief for the terminated wires and protects the IDC or solder connections from dust, snagging, and accidental shorting against the enclosure.
