Composite Engineer's Folding Rule

The Milwaukee 48-22-3802 Engineer’s Composite Folding Rule is the engineer/layout-focused version of Milwaukee’s folding rule lineup, designed for precision measurement, conduit work, and construction layout where decimal and angle reference markings matter.

Key Features:

• 78" total length (folding rule style) for extended layout and transfer measurements
• Engineer’s scale + imperial markings for dual-system measurement use
• Composite laminated construction for durability and water resistance
• Heat-stamped markings resist wear, fading, and abrasion on job sites
• Corrosion-free embedded joints that lock at 0°, 90°, and 180°
• Angle reference markings for common conduit bends (22.5°, 30°, 45°, 60°)

Performance Highlights:

• More accurate than tape measures for rigid layout and transfer marking
• Engineer’s scale allows decimal-based measurement workflows (useful in structural, civil, and electrical work)
• Built for repeat folding/unfolding without joint wear or looseness
• Angle markings make it especially useful for electrical conduit bending layouts

Typical Uses:

• Electrical conduit layout and bending reference
• Structural steel and framing layout
• Civil/engineering measurement transfer work
• Precision shop and field layout tasks
• Any job requiring decimal + angle reference measurements
