The Xtrasafe Quad Lock features a unique four lever design (2 levers on each side, one on top of the other). Stacking the levers on top of each other forces the operator to open the outside levers first because the inside levers can only be opened after the outside levers are open first. They cannot be opened at the same time.

Opening  the outside levers allows the male fitting to separate just enough to break the seal, while the inside levers will not allow the fittings to fully separate.  If there is pressure still in the hose, the operator will immediately see the potential problem. The operator then simply re-closes the outside levers letting the operator regain control of the situation.

If one was using a conventional camlock at this time, the fittings would completely separate causing a failure due to a 100% out of control situation. The results of such an accident caused by using old technology could cause personal injury and property damage.

Maxisafe Fittings are designed to prevent these types of accidents.
