Starrett 15″ Engineers/Plumbers Level

Description

15″ with Adjustable, Fixed and Plumb Vials

Specially designed for engineers, plumbers, and other mechanics, Starrett
No. 133 Levels combine three uses in one with their 3-level feature – a fixed
level, a plumb and an adjustable incline level.
Both the main level and incline level vials can be read from the side and the top.
The incline level tube has a hinged mounting inside the level frame. After
placing the level on any inclined surface it is adjusted to the “level” position.
The degree of incline is then indicated by the pointer at the end of the level
tube and read off a graduated plate.
The inch reading plate is graduated in 1/16″ per foot (1.6mm per 300mm)
and reads up to 2″ per foot (50mm per 300mm) incline.
Millimeter reading plates are graduated in millimeters per 250mm and read
up to 40mm per 250mm incline.
The base of the levels have an involute groove running the full length, which
provides a reliable seat for round work.
