The Milwaukee 9” Torpedo Level with Lighted Vials provides better vial visibility in poorly lit environments. Each vial is lit with bright dual LEDs and the high-contrast surrounds deliver clear readings. The level also has a durable aluminum frame protecting it from drops and harsh jobsite conditions. The 3 rare earth magnets on the frame make working with conduit and other metals easier; and the rubber wall grip grabs onto the surface when leveling trim, shelving, windows, and outlets. The level is powered with (2) AAA batteries (included) and the vials have an automatic shut off after 3 minutes to preserve battery life. The 9” Torpedo Level with Lighted Vials is backed by a limited lifetime warranty on the frame and vials and a 1-year limited warranty on the electronics.
