Granite Right Angle Box

Granite Right Angle Box

The Essential Production Tool for 90°Verification&Setup

Tool Definition&Practical Application

A Granite Right Angle Box is a specialized L-shaped precision reference tool designed specifically for rapid,reliable 90°verification in manufacturing,assembly,and quality control environments.Unlike full cubic square boxes,this configuration provides immediate access to internal and external right angles for checking perpendicularity of components,fixtures,and machine setups.It represents the optimal balance of precision,accessibility,and practicality for daily use on production floors and in toolrooms.

Design Philosophy:Precision with Practicality

L-Shaped Configuration Advantages

Unobstructed Access:Open design allows easy placement of components against reference surfaces

Internal&External Reference:Simultaneous access to both interior and exterior 90°angles for versatile measurement

Reduced Weight:Approximately 40-60%lighter than equivalent cubic boxes,improving handling and portability

Space Efficiency:Compact footprint maximizes utility in crowded work areas and inspection stations

Industrial-Optimized Construction

Reinforced Junction:Extra mass at the critical 90°intersection ensures long-term angular stability

Practical Wall Thickness:Balanced design provides adequate stiffness without excessive weight(typically 20-30%of overall dimensions)

Accessible Reference Edges:All critical edges positioned for easy indicator contact and visual inspection

Multiple Setup Orientations:Can be used horizontally,vertically,or on either side for different measurement approaches
