Endo Finger Ruler Span Measure Scale
Color-coded endodontic measuring ruler designed for accurate working length calibration and organized multi-operatory instrument management.
Key Features:
• Manufactured from anodized aluminum alloy with laser-etched graduations
• Available in red, yellow, and green color-coded variants
• Measurement range spans from 0–40mm for extended file calibration
• Full-length central slot maintains parallel file alignment during measurement
• Dual-sided millimeter scales allow left and right visual verification
• Suspension hole supports tray peg or instrument chain mounting
• Anodized finish resists fading during repeated 134°C autoclave cycles
• Long rectangular body improves measurement stability and scale visibility
Endo Finger Ruler Span Measure Scale
The Endo Finger Ruler Span Measure Scale is produced in three color variants; red (LS8-007), yellow (LS8-008), and green (LS8-009), each constructed from anodized aluminum alloy with laser-etched millimeter graduations. The body is a long, flat rectangular plate running the full measurement length from 0 to 40mm, the widest measuring range in the Leader Surgical endo ruler range. A full-length central slot channels the endodontic file shaft along the ruler body during measurement, keeping the file axis parallel to the scale and eliminating lateral drift at the rubber stop position. The Leader Surgical brand mark is printed on each color variant.
Dual millimeter scales flank both sides of the central slot, the left and right columns read simultaneously, allowing verification from either hand without reorienting the ruler. A suspension hole at the top of the body mounts onto tray pegs or instrument chains, keeping the ruler immediately accessible at the operatory without occupying flat tray surface. The anodized finish withstands full autoclave sterilization at 134°C without color fading or scale legibility loss across repeated cycles.
The three-color system: red, yellow, and green, serves a direct clinical organization function: each color is assigned to a specific operatory, tray, or clinician, preventing mix-ups across multi-chair practices. The Endodontic Ruler catalog category confirms this color-coded format as a standard multi-unit tray management solution in busy endodontic practices.
Endodontists use the Endo Finger Ruler Span Measure Scale during root canal treatment to set and verify rubber stop positions on K-files, H-files, and rotary NiTi instruments against the measured working length at each canal instrumentation step. Leader Surgical produces all three-color variants to identical 0–40mm scale-accuracy tolerances, ensuring consistent measurement output regardless of which color variant is in use.
What is an Endo Finger Ruler?
It is a specialized endodontic instrument designed for the precise measurement of root canal lengths and the adjustment of endodontic files, reamers, and gutta-percha points during dental procedures.
