Applications for Electrical and HVAC

Align Outlets and Switches Click for larger image

Align Outlets and Switches

Easily align outlets and switches, whether in residential or commercial/industrial applications. A horizontal line can be used in place of a chalk line or individually measuring each placement.

A line laser easily helps make sure everything is laid out in a straight line. Use a point-to-point laser to transfer reference points from the floor to the ceiling to make quick work of installing cable trays and ducts.

Install Cable Trays and Ducts

A line laser (in vertical mode) easily replaces a chalk line when installing switching gear or mechanical equipment, eliminating the risk of imprecise or smeared chalk. With one, quickly deployed line, all mounting holes in the floor can be drilled with a deft ease.

Conduit and rigid cable requires perfectly aligned holes on the floor and ceiling (or opposite walls), or else they will not fit. A line laser can be used to easily line up the center points of many holes at once. Alternatively, a point laser can be used to transfer a single point.

Lay Fixture Runs for Lighting Click for larger image

Lay Fixture Runs for Lighting

Long fixture runs for lighting can take a long time to lay out, especially if everything must be measured overhead with a ladder or a scissor lift. Using a point laser to determine reference points and a line laser to create a perfectly straight run will make the job a lot easier. Lasers will also make quick work of aligning and installing conduit.
