The Hobbs lowering device was first designed and manufactured in 1980 by Ed Hobbs. Tried and true, the device has been improved and re-designed over the years by Ken Johnson. The latest version is the H-2. This device is designed for lowering lines from 1/2" to 3/4" in diameter and has a working load limit up to 3,000 lbs. The H-2 offers smooth and precise rope control and a lifting capacity of 1,000 lbs. The heart of the device is the aluminum spool, which is designed for extreme impact loading, wear resistance and heat dissipation. It's mounted on a 1-1/2" solid steel shaft, with oil impregnated bushings for years of use. The H-2 comes complete with a 20' mounting strap (fits trees up to 6' in diameter), winch bar and detailed graphics explaining proper usage, ratings, warnings and safe operations. Weighs 58 lbs.
