Metal stand-offs will not break off in cold weather. Stand-offs 1/4" thick, avoid bowed studs and will not get hung up when the level is being stored or removed from storage. Stand-offs are raised off of the floor 1/2" so debris doesn't have to be swept away before use.
Fully sealed solid rail (six sided) extension system, eliminates deflection, extension crash, and delivers the smoothest sliding available
High visibility scale on both sides of the extension rail allows for fast set-ups and adjustments (8'1" , 9'1" , 10'1" , 12'1" etc.)
The plumb vial is permanently positioned 66-1/2" off of the floor and will not slide out of view when the extension is being used
Vials are guaranteed for life never to fog, leak or require adjustment
Patented epoxy locked vial system never requires adjustment
Frame side opposite the stand-offs is a level measuring surface and straight edge
