The JOHNSON LEVEL TOOL 415 is a 12-inch combination square built for layout, marking, and angle verification on the job site. The stainless steel blade carries permanently stamped English graduations that resist wear under field conditions. The head is molded from heavy-duty Structo-Cast plastic, a material chosen for its rigidity and resistance to impact. A reversible head design with a lock bolt and steel screw lets the technician position the blade quickly and lock it securely. A durable acrylic level vial is integrated into the head for fast plumb and level checks without a separate tool. Carpenters, electricians, plumbers, and general trade pros reach for this square during rough-in and finish work alike.
The 415 is suited for residential and light commercial construction and renovation work. It handles common layout tasks such as scribing lines at 90 and 45 degrees, checking depth, and transferring measurements. The English graduations make it compatible with standard imperial dimensioning used on most domestic trade drawings and cut sheets. The compact 12-inch blade length fits easily in an apron or tool bag, keeping it accessible throughout the workday.
Designed as a general-purpose 12-inch combination square compatible with standard imperial layout and measuring tasks common across carpentry, electrical, plumbing, and HVAC rough-in work.
No installation is required for this hand tool. Before use, verify the blade locks securely at the desired position by tightening the lock bolt fully. Keep the blade clean and free of debris to maintain accurate readings. Handle with care to preserve the calibration of the level vial.
