Ritherdon originally worked on the “Gas Grate” with Transport for London, as an enclosure for both cable management and prevention of gas seepage into the base of a traffic signal cabinet.  We have recently developed this concept into the Hinged Controller Base (HCB): a gas grate which opens right up to make feeding the cables into an external enclosure a much easier, faster and more comfortable job.

This cable management unit is suitable for any electrical enclosure where multiple (especially SWA) cables enter from below.  The best way to be impressed by the features and benefits of this product is to call us and arrange a demonstration and for more technical information.
