The PW-4 is designed for heavy duty use. It has two 15mm driveways, which are oriented at 30 and 45 degrees so that the user can always access the pedal, regardless of the position of the pedal.
Its asymmetrical head is made of chromoly steel for durability and strength. Apart from being very strong, it is slim to allow you to access all nuts. It has an extra long 35cm handle to give you the necessary strength to loosen the tightest pedals. The handle is vinyl lined to eliminate the risk of slipping, which happens with the flat handles of some wrenches.
