This is “The Lights,” Stabila’s heavy-duty Type 196 level equipped with two LED-illuminated vials, a level that combines optimal clarity with accuracy and durability. Two of three vials are lit by removable LED light packs. Plus, these vials never need recalibration, are guaranteed accurate for life and can be read in any direction with no change in accuracy tolerance, allowing overhead (vial down) measurements. Shock-absorbing end caps grip walls and do not leave marks, and are removeable?for scribing in corners and for reading tight header and sill openings.
