Starrett Webber Angle Gage Block Sets:

Webber Angle Gage Blocks come in three accuracy grades: croblox® Reference Angle Blocks (R grade)
with a 1 second accuracy, steel Calibration Grade Angle Blocks (C grade) with a 2 second accuracy, and steel Working Grade Angle Blocks (W grade) with a 5 second accuracy. Each grade can be purchased individually, or in sets that will measure in steps of 1 second, 1 minute or 1 degree to suit any need.

Croblox® Reference Angle Blocks with a 1 second accuracy are designed for optical use or as
reference standards for autocollimators, spectrometers, or other types of optical instruments.
These Angle Blocks are unsurpassed for use in aerospace, optical and precision instrument fields.

Steel Calibration Angle Blocks with a 2 second accuracy possess the same high quality as the
Reference Grade Angle Blocks but are manufactured from hardened tool steel for better economy.

Working Angle Blocks with a 5 second accuracy are designed for the shop or tool room.
Their longer gaging surfaces are made for use with an indicator. Additonally, these blocks reduce
set-up time and minimize error in grinding both simple and compound angles.
