Junction boxes include the Abox Pro 350-35 for IP66/IP69 and the WKE Rapid-Box HT fire-rated junction box for circuits that must keep working in a fire.
ABS and polystyrene enclosures suit indoor and sheltered use, polycarbonate offers impact strength and UV resistance, and IP69 versions resist high-pressure cleaning. Fire-rated junction boxes keep fire alarm and emergency lighting circuits working for a set time in a fire.
Cable entries, mounting plates and terminals are chosen with the enclosure to suit the installation.
