Description The most common wrench is a design that combines an open-end and adjustable profile. The combination of two single-size profiles compensates for the shortcomings of each individually. It is made in accordance with the DIN 3110 standard from chrome-vanadium steel, hardened, has a chrome-nickel coating, and fully complies with GOST 2838-80. Upon customer's request, combined wrenches of the "W26" series with sizes up to 105 mm can be supplied.
