The STABILA® 24-Inch Heavy-Duty Level Type 196 is designed to provide outstanding readings while it handles harsh jobsite conditions. It features two durable end caps which prevent damage from dropping it or impacting with hard surfaces. The box-beam level's ends are removable so you can easily get flush measurements. This level includes two vertical vials to determine plumb, and a horizontal vial for finding level. All of this Stabila level's vials are locked in, which means you don't have to calibrate them. The ergonomic hand grips prevent strain and fatigue while you work, so you can move on to the next step of your project with full energy. The vial housing is visible from a wide angle, which lets you use it in multiple positions.
