  • MULTI-PURPOSE PLUMBING, MEASURING, LEVELING AND SECURING APPARATUS
    Publication number: 20090106993
    Abstract: An apparatus for measuring, leveling, securing and plumbing. The apparatus contains a slide element slidably mounted to a body element. The body element is fixed to a base element. The slide element defines a viewing channel for viewing a side level fixed to the body element. The slide element has a pair of longitudinal trapezoidal rails fixed to the back of the slide element and running its length. The body element has a pair of longitudinal trapezoidal channels along the front of the body element. The channels within the body element receive the rails of the slide element to slidably fix the slide element to the body element. The slide element may be moved along the body element to a set position, the apparatus aligned, and the slide element locked into place for measuring or plumbing.
