The Indi-Square Company/Genesee Manufacturing produces squareness and vertical straightness instruments which feature an exclusive proven anti-friction lifetime sliding mechanism.  Manufactured in Rochester NY, the two models rapidly indicate squareness and straightness with a minimum of effort and a maximum of accuracy. Calibration of the instrument can easily be accomolished with the aid of a granite square.

• Hardened, ground and STABILIZED gaging column with two extremely accurate ball spline groves, ground in front and rear. It is held at the bottom in a spring loaded spherical ball seat. The top is held by two highly accurate eccentrics for adjustment.
• Completely ANTI-FRICTION, ball recirculating, gaging head. The balls circulating against the spline grooves in the gaging column. The rear ball system is spring loaded, constantly eliminating any play or shake. THIS IS A VERY IMPORTANT FEATURE, GUARANTEEING NEW ACCURACY FOR YEARS OF SERVICE.
• Eccentrics for adjusting the gaging column front to back and side to side. One in the side of the unit and one in the rear. They are adjusted by simply turning eccentrics with allen wrench supplied, and tramming indicator up and down granite master (accessory). This is done very quickly. Once calibrated it should not be necessary again, unless surface plate is not accurate.
• Adjustable indicator bracket to position indicator.
• Indicators: Use your choice. However we recommend the vertical type (easier to read and closer to the head for rigidity) with the universal dovetail clamp.
• Knob for raising and lowering head
• Hardened, ground and lapped feet. THEY ARE RIGIDLY FIXED TO THE BASE CASTING. Adjustment is made at the top of the unit with no loose connection at the surface area to disturb accuracy.
• Front pads for moving instrument sideways. For use in certain fixture applications
