Tekox Terminal Strips Safety Blocks and Porcelain Blocks

Great electrical installations don't fail because of the major components. They fail because of the small ones that didn't get enough attention.
It's easy to focus on the big-ticket items during specification — and let the terminal blocks become an afterthought. But inferior connection components have a habit of making themselves known over time. Loose connections, degraded insulation, premature failure.

Tekox engineer their terminal strips, safety blocks, insulated strips, and porcelain blocks to the standards your installations deserve. Available now from Demesne Electrical — get in touch and we'll show you the range.
