The Bosch GRL18V-34NK Green-Beam Horizontal/Vertical Rotary Laser Kit delivers precision leveling, vertical alignment, and slope matching across demanding commercial jobsite layouts up to 1,500 ft. in diameter. Engineered for general contractors, civil excavators, concrete trades, and interior framing crews, this multi-axis laser handles exterior grading as well as interior plumb and squaring applications.

Featuring a bi-color LED interface, the laser provides clear visual confirmation of operational status by showing green for leveled conditions and red when establishing manual slope inclinations up to 15% along the Y-axis. Built-in Bluetooth connectivity pairs directly with the Bosch Leveling Remote App, giving operators wireless remote control over slope dial-in, rotational speed, and standby modes from a smartphone.

The housing is IP66 rated for complete dust sealing and high-pressure water resistance, and the frame is drop-tested to withstand a 5 ft. tripod tip-over. Flexible dual-power operation allows continuous field productivity using either the four included C alkaline batteries via the BA18-C adapter or any Bosch 18V lithium-ion battery.

Features & Benefits

• 1,500 ft. Working Range: Delivers long-range coverage with accuracy up to +/- 1/16 in. at 100 ft. horizontally and +/- 1/8 in. at 100 ft. vertically when paired with the LR20 receiver.
• Horizontal and Vertical Orientation: Functions in flat and upright positions to handle site grading, footing layout, vertical plumb alignment, and partition squaring.
• 15% Y-Axis Slope Matching: Single dial-in slope capability establishes slopes up to 15% for drainage trenches, driveways, and accessibility ramps.
• Bi-Color LED Display: Provides color-coded interface feedback, illuminating green when level and red when set to slope mode.
• Bluetooth Connectivity: Connects to the Bosch Leveling Remote App for smartphone control of laser functions from a distance without touching the tripod.
• IP66 Ingress Protection: Fully gasketed housing prevents dust intrusion and withstands heavy site spray and rain.
• 5 ft. Tripod Tip-Over Resistance: Ruggedized impact structure cushions core optical components against accidental jobsite falls.

We reserve the right to determine the fastest and most cost-effective manner of transportation for all orders that qualify for free shipping. Our shipping carriers cannot deliver to PO box or U.S. military post office box addresses, such as APO and FPO, so we require a physical street address for delivery.
