The Workhorse of Your Wiring: A Tradie's Guide to Junction Boxes

Every professional electrical and data installation relies on secure, protected connection points. Exposed wiring and unprotected terminals are a recipe for faults, damage, and a non-compliant job. The humble junction box is the workhorse enclosure that keeps these critical connections safe, sound, and sealed from the elements.

Tough, reliable, and built for the job, SCHNAP’s range of Junction Boxes covers everything from compact indoor connectors to heavy-duty, weatherproof enclosures for the harshest Aussie conditions.

A Box for Every Condition: Understanding IP Ratings

Choosing the right level of protection is critical, especially for outdoor or industrial work. Our range includes various IP (Ingress Protection) ratings to suit your needs:

  • IP54-rated boxes are splash-proof, making them suitable for protected outdoor areas like under eaves or in carports.
  • IP65-rated boxes are fully dust-tight and can withstand jets of water, making them the perfect choice for exposed outdoor locations, workshops, and wash-down areas.

The Right Fit for Your Install

No matter the challenge, we've got a box to suit the job.

  • Deep Conduit Boxes: Need extra room for a heap of wires or bulky components? Our deep junction boxes provide the additional space you need to keep your connections tidy.
  • Angled Fittings: For those tricky runs in tight corners or against other services, our angled entry boxes make installation a breeze.
  • Knockout Models: Save time on drilling with our convenient knockout models, allowing for fast and easy conduit entry.

Built Tough with the Right Materials

Our junction boxes are engineered to last. We stock a variety of options to match your application, including durable ABS, standard PVC, and high-safety flame-retardant plastics for added peace of mind in critical installations.
