All the T series junction boxes are UV-resistant. They are made of a thermoplastic polypropylene plastic with plug-in seals made of ethylene vinyl acetate (EVA). This plastic is soft, which means that it is malleable. This allows installation of cables either directly through the 4 x M25 seals, or the seals can be cut with a knife at the pre-marked points, in order to create an insertion opening for cables or pipes. In addition, cable glands can be pushed through the openings instead of the seals and locked with a locknut from the inside.
The cable junction boxes can be screwed onto an M6 thread or be mounted on mounting plates in the openings on the floor using steel screws 3.5 x 9.5.
