The 1399G14 is a white, short spacer with a mounting hole, designed for use with Powerpole® 15/45 series connector housings. This accessory is used to separate individual housings when assembled into a block, which helps minimize derating under high power conditions. It is also recommended for squaring off a block of housings for proper fitment within connector shells and mounting clamps. The integrated hole allows the assembled connector block to be fastened directly to a surface, providing a secure mounting option.
