## Description

The RJ-12/RJ-11 Telephone Round Panel Mount Extension Cable provides a simple way to add a panel-mount telephone connection to project enclosures. The round panel-mount design fits a standard drilled hole of approximately 30 mm — no custom oval or square cutouts required. Unscrew the plastic nut, insert through the panel, and re-attach to secure the jack. The cable provides a full pass-through connection with the plug wired in the same order as the jack. It accommodates panel thicknesses from a few millimetres up to 16 mm, and the plastic lip conceals the drilled hole for a clean finish.
