The STABILA Type 96 M Mag Jamber Set (Model Number: 38532) is a magnetic spirit level set designed for commercial door installation and door jamb setup. This set gives you two purpose-picked lengths (32 inches and 78 inches) so you can plumb, level, and mark door frames fast without juggling multiple tools.

The jobsite advantage is the rare-earth magnet system. When you are working around steel frames or hinge hardware, the levels can hold themselves in place so you can focus on fastening and shimming instead of babysitting the tool. The 78-inch length is sized to match standard 80-inch door openings, which makes it easier to check the full jamb without stacking shorter levels.

Accuracy is where these earn their keep. STABILA s LOCKED VIALS installation technology permanently locks the vials into the frame for long-term reliability, and the measuring accuracy is b11/32 inch at 72 inches in both normal and reverse position. That means you can flip the level and trust the reading, which matters when you are chasing a twist in a jamb or verifying a reveal.

The frame is a heavy-duty aluminum box-beam profile built for construction sites, with an electrostatic powder coating that is easy to wipe clean. Two coated measuring surfaces help you measure in different positions while being easier on delicate surfaces. Rubber end caps protect the profile against impact, and the end-cap design supports flush measuring when removed.

Both levels include horizontal and vertical vials for plumb and level checks, and the vials are designed for visibility with transparent, hard-wearing acrylic glass and fluorescent vial fluid. For long runs, the 78-inch level includes hand grips to make it easier to handle and reduce strain when you are setting multiple openings in a day.

If you hang doors, set frames, or work commercial interiors, this is a purpose-built set that saves time and rechecks. If you only level cabinets once a year, it is overkill. But for crews doing doors regularly, the magnetic hold and full-height 78-inch check are the real payoff.
