32" & 78" Heavy Duty Aluminum Box Level Door Jamb Set

MODEL #:  1717-3278

The workhorse of our level line, this door jamb set is a dependable performer to get you through any doorframe job. It features a 32" level for leveling headers and a 78" level for leveling jambs. Both levels feature reinforced aerospace aluminum alloy frames  that provide the durability needed on even the roughest jobsite, and magnified vials with 320⁰ visibility for easy viewing when working overhead. For dimly lit jobsites, you'll love Johnson's patented Glo-View® technology; the vial surrounds glow in the dark to maximize vial readability. This door jamb set features strong rare earth magnets that hold the levels securely in place on ferrous surfaces.
