摘要: A line-marking device (100) includes a chalk line (200) that is held in an elongated frame (170). worker can position and align the device, then snap using manually operated trigger (650) to leave mark on surface (530), such as wall or floor. An adjustable level (115) (170) be rotated dial desired angle for line. The may provided setting independently of device. laser (125) carried at tip (120) (or elsewhere on) allow aligned with reference (145). Respective markings (176, 177) edge regions rails (171, 174) indicate angular guide bar (500), or, protractor (810, 810a) setting.
