The CRL Plumb Perfect Level Tool was invented by a glazier who was looking for an easy method of establishing the amount or distance a wall is "out-of-plumb" from top to bottom. This figure is necessary for many types of glazier installations, however it is most important when laying out storefront and shower installations. CRL engineers took this idea, then redesigned and improved upon the original concept to come up with the CRL Plumb Perfect. The end design is a simple "one person" tool that can be quickly extended to the correct height, trued to plumb, and then with a twist of the scale locking knob you can extend the scale to read the amount of "out-of-plumb" of the wall from top to bottom.
The CRL Plumb Perfect is an expandable aluminum frame that has a built-in level, along with a calibrated horizontal protruding steel scale. The frame has a minimum height of 56" (1.4 m) and a maximum extended height of 96" (2.4 m) to fit most common install jobs.
Designed by CRL engineers, made in Los Angeles at CRL Manufacturing, and calibrated by CRL technicians, this is an accurate and durable tool that will save time and money during each installation.
