A level display assembly includes a level with an elongated body having a hand hole along the length thereof and at least one level indicator mounted thereon. Extending about the body of the level is an elongated tubular sleeve which has a hinged flap formed along its length. The flap has its free end extending into and engaged with the level about the hand hole to limit relative sliding motion therebetween. The sleeve may also have apertures therein aligned with the level indicators disposed thereunder to permit viewing of the indicators therethrough. The sleeve is formed from a unitary blank with a series of fold lines which allow it to be formed into a rectangular cross section, and the flap is hinged along one of the fold lines. The material from which the sleeve is formed provides sufficient resilient deflectability to permit the flap to be pulled through the hand hole to abut the opposite surface thereof.
