CRL PLF1 Plumb/Level Finder Gauge

Use this handy set of CRL Plumb/Level Finder Gauges to determine the amount or distance out-of-plumb a wall or floor is when using your bubble vial level.
Set includes: 1/16″, 1/8″, 3/16″, 1/4″ and 3/8″ (1.6, 3.2, 4.8, 6.4 and 9.5 mm) thick neoprene gauges.
Simply hold the level tight against a horizontal or vertical surface. True the level and then use the thickness gauges to determine the amount out of level or plumb the surface is at that point. You can combine gauges when necessary for gaps exceeding 3/8″ (10 mm).
