Checking a door rough opening twice before the drywall goes on

Accuracy

A door rough opening that is a half inch narrow is a five-minute fix while the studs are still open and a demolition job once the board is hung and taped. The T1R Range shoots a laser to the far jamb when the opening is too wide to reach and reads as a tape when it is not, so both checks come off one tool. Every figure is saved, which is what turns a walk through a floor of openings into a record rather than a memory.

Door rough openings are checked in a timber-framed house before drywall, interior partitions still open studs with the roof deck visible above. The tool is held up in the opening and a reading taken, then taken a second time to confirm. Several openings along the same run are checked in turn.
