Features & Benefits

  • GL412N / GL422N are grade plus horizontal and vertical lasers. Simple, accurate dial in grade from -10% to +15% (Single GL412N, Dual GL422N)
  • Up to 2,600 ft (800 m) working diameter which increases productivity by reducing need for multiple set-ups on a large job site
  • Fast setup, minimal training time and automatic self leveling minimize operating costs and boost productivity
  • Highly rugged design and patented lighthouse sealprotects the rotor head and glass andoffers superior drop and weather protection for reduced downtime
  • 2-way full function remote control allows grade changes to be made from anywhere on the jobsite
  • Temperature calibrated for high accuracy over wide temperature changes
  • IP66 dust and water-proof to withstand harsh jobsite conditions
  • Customizable with choice of HL760, HR320 or CR600 receivers
  • Mask mode eliminates interference from other crews on the jobsite
  • Automatic Grade Match and PlaneLok
