Spectra Precision CTO-0319-4310 DE Measuring Rod 15-foot Feet, 10ths and 100ths
How they Work:
Direct Reading/True Elevation Grade Rod
Direct Reading, or True Elevation (also known as Lenker style) is a Grade Rod with a moveable tape face allowing you to set the actual benchmark elevation, or any elevation, above or below the bench into the rod. The actual true elevation above sea level is read on these rods, thus eliminating errors caused by adding or subtracting. Since no math is involved, grade shots are much faster than conventional style rods. On most jobsites, the bench elevation is typically established by survey, and all elevations on that project are above that or below primary bench elevation.
Spectra Precision CTO-0139-4300 SPECIFICATIONS
- Length 15-Foot
- Measurement Feet, 10ths and 100ths
Spectra Precision CTO-0139-4300 Features & Benefits
- Direct Elevation (DE) rods are made of ash and aluminum
- Laser DE rods feature a side rail for attaching optional bracket for laser receiver
- Continuous tapes are stainless steel
- Latch in back locks the band in any position to match a benchmark elevation
- Wear resistant Delrin® end-rollers
For use with a laser detector. There is a special rail slide and optional detector bracket (shown below) that lets the laser detector travel the full working length of the rod. This allows faster and easier readings because it takes the awkwardness out of having to loosen the detector, move the detector, then tighten the detector for each reading.
