Display family photos and artwork, hang decorative items, and mount shelving with professional results using the BLACK+DECKER BullsEye auto-leveling line laser with AnglePro technology. The class II laser is designed to project horizontal and vertical laser level lines automatically, which means you won't have to make manual adjustments. Plus, AnglePro technology provides an automatic reference for angled lines when hanging items along a staircase. Rubber overmolds add protection in case you drop it on the ground, while a built-in backlight enhances the visibility of angle reference points. For added convenience, this auto-leveling line laser includes a handy wall mount and attachments.
