One tool for door, window and opening dimensions

Choosing a Tool

A day of openings is a mix of jobs: a door width here, a window height there, a rough opening that has to be checked against the schedule. Swapping tools between them is what puts figures in the wrong column. The T1M Utility handles all three with its removable reference square for squaring off a jamb and a saved list that keeps the readings in the order taken, so one tool covers the walk and one list goes back to the office.

Openings are measured in a finished interior with tiled floors and painted walls, the tool worked across a doorway and along a wall. The display steps up through the fifties and sixties as the blade is extended. The reference square stays on the tool throughout and each reading is saved before the next.
