Hunter Spring Static Bonding Reelsprovide the automatic retraction andcompact storage of 50, 75 and 100 footcable and clamp assemblies. Designedto function under extreme environmen-tal conditions, the 50 and 75 foot cablelength models meet USAF SpecificationMIL-R-83232B.

By utilizing a SPIR’ATOR® spring,rather than a power spring, for exten-sion and retraction, Hunter SpringStatic Bonding Reels are smaller andlighter than the original military specifi-cations. This reduced size and weightmake Hunter Spring reels easier to lo-cate and mount on vehicles. A patentedlatching mechanism holds the cable atany desired length. A slight pull on the

cable releases the mechanism causingretraction. Retraction need not beattended. The retraction speed isautomatically governed by a specialbrake assembly designed to limit theretraction speed from two to seven feetper second. Steel components and acantilever-type frame, which supportthe reel assembly, are designed tofunction under the most adverse condi-tions. Baked-on MIL spec red finish andgasketed drum construction protectoperating parts from corrosion. Bearingsurfaces are permanently lubricated.
