Recommended Applications
Surface Wiring Systems: Exposed conduit installations in basements, garages, workshops, and utility areas
Industrial Facilities: Factories and warehouses where surface-mounted conduit is standard practice
Commercial Renovations: Retrofit electrical installations without wall demolition
Outdoor Covered Areas: Covered patios, carports, and semi-outdoor spaces (with proper weatherproofing)
Temporary Installations: Construction sites and temporary power distribution systems
Circuit Branching: Distributing power and lighting circuits in multiple directions with 3-way or 4-way configurations
Installation Guidelines
Plan Junction Location: Mark box position at conduit intersection points; ensure accessibility for future maintenance
Mount Box to Wall: Secure the junction box directly to wall surface using appropriate screws and anchors; ensure box is level and firmly attached
Connect Conduits: Run surface conduits to the box socket openings (3-way or 4-way as needed); use appropriate saddles to support conduit runs
Pull and Connect Wires: Feed wires through conduits into the box; make connections using wire nuts or terminal blocks; leave adequate wire length for future work
Secure Lid: After completing all wire connections, attach the lid using the provided screw; ensure tight closure to protect connections from environmental exposure
