The Schley Products Extension Protectors Deluxe Kit, No. 15950, is designed to protect any length 1/2" drive extension should it be otherwise used as a hammer drift. Different from the company's Extension Protectors Essential Kit, the Deluxe Kit includes a custom female hammer that accepts the three interchangeable hammer heads in the kit. These hammer heads are made of nylon, aluminum, and steel for multiple applications. The extension protectors are precision machined from heat-treated alloy steel and allow the use of a normal socket extension as a drift without causing damage. The hammer set is versatile, works with ordinary 1/2” drive tools, and the hammer heads are designed for a variety of uses.
