Peco Products PL-82 Power feed joiners - Code 55/80 (x4 pairs)
These joiners are used in place of standard rail joiners, and remove the need to solder your wire to the track where extra power is required. All that is needed is to remove the existing joiners that are attached to the track, and after drilling a hole through the baseboard, just feed the wire through. You can attach these to other lengths of wire if extra length is needed. Each joiner comes with approx 200mm (8 inch) of wire.
