HELO ADJUST is a restraint device intended to limit passenger movement while traveling inside of helicopters when seatbelts or other restraint systems are not available or being used. Its unique aluminum adjuster allows the operator to easily extend and/or shorten the tether with one hand. The EASHOOK OPEN connector supplied with the tether includes an automatic locking feature which facilitates rapid connection/disconnection from an anchor point. In emergency situations, the operator can also disconnect from the tether by releasing the snap shackle. The HELO ADJUST meets the performance criteria and testing validation for the safety belts and lanyards program set by the Program Manager, Special Operations Forces Survival, Support & Equipment Systems (PM-SOF SSES) office at the U.S. Army Soldier Research Development, and Engineering Center, Natick, MA and is included in the Approved Product List.
