SlabDoctor 4-Way Directional Adaptor

The Patented SlabDoctors' 4-Way Adaptor allows the user to extend the Level in 4 Directions: East, West, North & South. A conventional level cannot do this. If you need to check a concrete slab for humps, dips, slope, grade or elevation, you may require your Level to do this in more directions than just one. This Adaptor will allow the user to extend his Level around a corner, down the hall, or into another room. The Adaptor is equipped with a Latch Assembly on each end; therefore when connected to a Level, it can be locked into place and will not move.
