The SADP quick connect adapter allows selected monorail pendants and elements to be connected to a linear track system. The adapter is conencted to the track by twisting as you would a regular fixture, then the jack from the light fixture or pendant is inserted into the adapter and tightened by hand. This is a perfect alternative for smaller applications that require a straight run and convenient mounting options. Since linear tracks provide low voltage power (they are connected to transformers) no separate transformer is required for the low voltage lights attached to the track using the SADP. Accepts all WC "quick connector" fixtures.
