All Bridgewerks power supplies and controllers are designed to
quickly and easily disconnect with this plug, making it simple to take
the unit indoors when not in use. The contacts are gold plated to ensure
long lasting wear outdoors. The plugs can be “piggy-backed” (one on top
of another) for additional connections. One plug is supplied for each
track, extra plugs are available from your dealer or direct from
Bridgewerks.
