SK X-FRAME design spreads the work load evenly across the wrench body in the same way that an I-beam spreads a load for a bridge or building. This innovative structure allows for unprecedented strength that exceeds ANSI specifications by 5 times.
Comprised of six pawls that operate in a clocking mechanism to ensure that two of the pawls are fully engaged with the ratchet teeth at all times.
Two pawls are always partially engaged and the final two pawls are disengaged at all times, resulting in the smallest arc swing in the industry; one third of the competition.
Swing enables work in tight spaces that are unavailable to other wrenches.
