The Delkim NiteLite Pro Illuminating Hanger evolved from the original NiteLite and took three years of intensive development and field testing to perfect. The challenge was to find a way to make a version of the original NiteLite with the advantages of a cable assembly that performed as a lightweight chain. Not as easy as it sounds. After much research, particularly into the medical endoscope field (ouch!!), nothing suitable was found so we had to invent something new, the CatFlex cable assembly. This gives good tensile strength and allows the fine wires needed to connect to the Delkim Plus range bite alarm to be protected and encased in a flexible black stainless steel coil. The complete assembly hangs in a perfect Catenary+ curve.
