The design gives it more torque so you can get it tighter on the fitting and allows it to lock down. If that is not enough the features keep coming, check out the belt loop hook which allows you to carry it at all times and the other end of the wrench is equipped with Dzus tool to pop panels loose for last minute adjustments.
Actual size is 6.50" x 2.75" with a jaw opening of 1.25" and ultra light at 6.6 oz. Great for carrying up to the starting line.
