JB2W Junction Box


90 × 90 × 49 mm

These enclosures can only be purchased in pack quantities of 10 and are subject to minimum order values which are displayed in your basket.

The JB series of junction box are designed to be maintenance free and corrosion resistant making them ideal for both indoor and outdoor use.

The aesthetic design maximises the internal installation space and the push fit fixing allows easy assembly. The larger JB6 enclosure can be supplied with fixing screws for added security.

The junction boxes are moulded in Polypropylene and benefit from an internal TPE skin which covers the cable entry knockouts and existing wall mounting holes in the base of the enclosure. This TPE skin gives the JB series IP65 rating and allows the user to insert wires, cables and conduits with a diameter up to 20mm directly without the need for a cable gland whilst maintaining the IP65 rating. This flexible membrane also means no cutting or breaking is necessary to install a cable gland which can be screwed directly into the enclosure without the need for couplings or locknuts.

Mounts in the base of the enclosure are suitable for fixing both PCB and terminal blocks.

Two size variants are available in grey and white. All of our junction box enclosures can be modified to your exact requirements including CNC machining and silk screening. Email sales@evatron.com or call 01908 325100 for more information.
