 Direct Reading Rod aka LENKER Rod


WHAT IS IT AND WHY DO I NEED ONE? 

A Direct Reading Rod is often referred to as a Lenker Rod. The term Lenker Rod comes from an older style of direct elevation-reading grade rods, which are designed to allow surveyors and construction professionals to read elevations directly without needing to calculate differences manually.

Key Features of a Lenker Rod (Direct Reading Rod):

  • Displays actual elevations instead of incremental measurements.
  • Commonly used with automatic levels, laser levels, and total stations.
  • Allows for quick elevation readings, reducing calculation errors in the field.
  • Often available in tenths or inches graduations, depending on the region and industry preference.

Laser Line Manufacturing is well known for producing Direct Reading Rods, including Lenker-style rods, designed specifically for grading, site prep, and laser leveling applications.
