This Hampton Bay Linear Track Floating Power Feed provides power to a linear track section (sold separately). This power feed features a 3 BUS, EC/H series compatible track adapter that allows for easy installation to an existing electrical junction box. The canopy is 5.71 in. Dia which is more than enough to cover that unsightly junction box hole. The power feed is rated for up to 2,400-Watt which makes expanding the track system and adding additional track heads, a cinch. Can be ceiling or wall mounted. Use when building your own system or simply replace that outdated square power feed on your existing track system.
