ABSTRACT:
A laser detector and grade rod coupling device is disclosed. The laser detector and grade rod coupling device can be compatible with laser detectors having different sizes, different shapes, and/or different relative positions of their laser targets. The laser detector and grade rod coupling device can include a height-adjustable bracket, a backing, and a flexible strap. The size of a laser detector opening between the backing and the flexible strap can be adjustable. A method for attaching a laser detector to a grade rod also is disclosed. This method can include positioning a laser detector against a bracket of a laser detector and grade rod coupling device and adjusting the height of the bracket until a laser level marking on the laser detector is aligned with a grade rod measurement indicator on the laser detector and grade rod coupling device.
