Constructed out of a magnesium mainbody, the SLS150Mg has been engineered to be durable and extremely lightweight. The tool weighs only 2.6 pounds making it maneuverable and easy to work with during extended periods of use. An integrated nose-mounted LED allows you to see in poorly lit areas and still be able to fasten efficiently and accurately. The oil-free motor of the SLS150Mg saves time on routine maintenance and ensures no oil spillover on the work surface. The stapler drives 18-gauge, ¼" crown staples from ½" to 1-9/16" in length.
