48" Big J Pro® Heavy Duty I-Beam Aluminum Level

MODEL #:  1253-4800

Professional finish carpenters prefer Johnson levels with removable endcaps because you can scribe a perfectly straight line directly into a corner. Historically, this feature was only found on box levels - but Johnson has raised the bar again by offering the industry's first I-beam level with a removable endcap. The level is also field serviceable; replaceable cover plates and replaceable acrylic vials ensure your level is always ready to work for you. To make this level as easy to use as possible, the oversized 1/2" vials come equipped with Johnson's SurroundView® technology for maximum visibility along with a top read window allowing the user to stand over the work to view the vials. The GripTight™ non-slip end caps allow you to hold the level firmly in place with just one hand, and the large comfortable rubberized hand grips provide a comfortable, sure grip every time.

This I-beam level is a perfect fit for general contractors and drywallers, although its versatility makes it a must-have for homeowners as well. Its GripTight™ end caps hold the level securely in place with just one hand and are removable, making them ideal for finish carpentry work when scribing lines into corners. This non-magnetic level is preferred when working with wood. For use on steel studs or doorframes, consider the magnetic model 1254 I-beam level.
