A pipe laser can be set up in a few different ways. The first one is with an instrument being set up inside the pipe that’s at least 6 inches in diameter, but it can also be set up on a tripod. If you need it to go inside a manhole, you can also set it up on a trivet plate or spreader bar. If you’re looking for a Topcon laser or any other type of surveying tool, be sure to look at what we have at Engineering Supply.
