description: The Milwaukee Shoulder Strap is for use with the M18 FUEL String Trimmer (2725-20) and the Milwaukee M18 FUEL Power Head with QUIK-LOK (2825-20). The strap is padded and transfers the weight of the tool to the user's body. This increases user comfort and reduces fatigue during extended use.depth: 9 inheight: 3.25 inwidth: 2.5 in
