As the industry leader, Stabila has improved on the "world's best level" with the new type 196 series. The accuracy is certified, top and bottom readings and sports a new rubber hand grip design. Promo Level Pack 37532 includes 37478 - 78-Inch ideal for installing door frames, and 37432 - 32-Inch level for installing headers, sills and thresholds. A special vial housing design lets you read these aluminum levels from a variety of different angles so you can work in tricky spaces. The hand grips have a rubberized cover for your comfort. These heavy-duty levels come with rubber end caps to prevent damage from impacts or being dropped. The end caps grip up against walls while they also reduce instances of gouging or marring drywall and other delicate surfaces. You can remove the end caps to provide greater accuracy for flush measurements. This promotional set is becoming the preferred lengths for levels for the homebuilders of the future.
