Product Description

The System 99 “Head unit” utilizes a stationary block in which the main pulley is mounted on a 4.75″ by 8.5″ by 3/8″ thick aircraft aluminum backing plate. The head unit weighs 3.5 pounds and provides 360 degree portability. It is so flexible it allows the user to move at any angle and in any direction. The large pulley on the head unit on the System *99* is a friction brake head block assembly that consists of a 3.5″ diameter by 2″ deep aircraft aluminum capstan roller drum. Made in the U.S.A.

  • Mounted on a 4.75" by 8.5" by 3/8" "thick aircraft aluminum backing plate with an offset bend so it hangs straight under load.
  • Mounted inside the drum is an anti-reverse spin lock, also known as a Sprague Clutch.
  •  Rope containment area of the drum is 3/8" thick.
  • The rope, capstan, and drum all ride on a 3/4" steel carrying bolt, which is supported on sealed ball bearings.
  • Three ‘Teflon’ ® coated rope guides located around the drum keep the rope from tangling or overlapping and tracking properly.
  • All the aircraft aluminum components are coated with a MIL-SPEC coating to resist corrosion.
  • Weight 3.5 lbs.
