The Johnson 48-Inch Bubble Level 1748 has a magnetic base and several other features that help you find precise plumb and level. It has a durable aluminum frame, protective end caps, 2 built-in handles, and replaceable cover plates. Results are gauged using 3 replaceable acrylic bubble vials. You can view the vials through the glass lenses of 3 sights or windows, plus an additional top-view window.
The Johnson magnetic bubble level attaches to ferrous metal surfaces. This gives you the option to work hands-free. You can use this to your advantage, especially helpful if you need to multitask. It also comes in handy if you are working in a limited or awkward space that will not accommodate both you and the tool. You can also use this feature to keep track of nails or if you work with metal framing.
This aluminum level handles rough environments well and will last for many years. The rigid frame serves as an excellent guide and provides steadiness that helps maintain accuracy. Shock-absorbent end caps offer protection on the job site, serving as buffers from friction and drops. And, the vials standup well to impact and resist breaking or leaking.
Multiple Viewing Options
The Johnson spirit level provides flexibility in reading its accurate results. Its 3 standard windows are viewable from both sides, plus it has a top-view window above the level vial. Overall, the results are viewable from almost any angle. This comes in handy if you are working under a cabinet, leveling an overhead beam, or in a tight corner.
This I-beam level comes complete with a limited lifetime warranty.
