Brand: Intermatic | Manufacturer Part Number: PJB4175 | Big Frog Supply SKU: PJB4175
Product Overview
The Intermatic PJB4175 is a polymeric pool and spa junction box designed to organize connections for up to four compatible low-voltage lighting fixtures. Its watertight multifixture enclosure supports properly installed pool, spa, underwater-lighting, and landscape-lighting applications where several flexible fixture cords transition to approved nonmetallic conduit. The black plastic construction resists corrosion and provides more connection capacity than the smaller two-light PJB2175.
An easy-access internal ground bar helps organize required grounding connections. The box accepts flexible cords and nonmetallic conduit from 1/2 inch through 1 inch and can be mounted using compatible bracket, post, rod, or wall arrangements. Intermatic’s PA114 wall/post mounting bracket is sold separately. This product is a junction box only—it does not include a transformer, timer, or lighting power supply. Any required pool-light safety transformer and control equipment must be selected separately for the connected fixtures and installation.
