Will the 900 lbs magnetic holding force keep my receiver secure during active grading and blade vibration?

Yes—900 lbs of holding force is engineered specifically for light to mid-range grading operations where blade vibration and ground contact are normal. Keep the blade surface clean of dirt and scale to maintain full magnetic contact; reduced cleanliness directly reduces holding strength. Test the mount before starting grade work to verify secure attachment.

Can I use this mount with both LR and Bullseye receivers, or do I have to choose one?

The ATI-991364-02 is compatible with both LR and Bullseye laser receivers, so you can swap between receiver types as needed. Each receiver must fit securely into the mount housing—verify compatibility with your specific receiver model before operation.

Do I need to drill holes or weld this mount to my dozer blade?

No—the ATI-991364-02 is designed for tool-free magnetic attachment to flat-back dozer blades with zero permanent modification. Simply clean the blade surface and position the mount; magnetic force secures it in place. You can reposition or remove it anytime without fabrication work.

What if my dozer blade has paint, rust, or scale on the surface? Will the magnet still hold?

Paint, rust scale, and dirt reduce magnetic contact and holding force. Clean the blade surface thoroughly before attaching the mount—use a wire brush or scraper to bare metal where the mount will sit. Regular blade maintenance keeps magnetic holding strength at full capacity throughout the day.

Can I reposition the receiver mid-operation without removing it from the dozer?

Yes—the magnetic design allows you to slide or reposition the receiver and mount without tools or disassembly. This is valuable when grade conditions change or when you need to fine-tune blade control. Keep the blade surface clean to maintain magnetic holding force during repositioning.

How does this mount compare to welded or bolted receiver mounts?

The ATI-991364-02 saves setup time, eliminates fabrication delays, and allows equipment to move between machines without rework—welded or bolted mounts require site-based fabrication and permanent blade modification. The trade-off is that magnetic mounts depend on clean blade surfaces and are best suited for light to mid-range grading rather than extreme-duty applications. For most contractors managing multiple jobs or fleets, the speed and flexibility of magnetic mounting outweigh the limited weight capacity.

FIELD APPLICATIONS

What contractors use this grade lasers for

Precision Grade Control on Active Dozers

Grading contractors use the ATI-991364-02 to hold laser receivers steady during blade operation, ensuring consistent height control without receiver slip during active cutting or fill work. The 900 lbs magnetic force keeps the receiver locked in place through blade vibration and ground contact.

Multi-Equipment Fleet Management

Contractors operating multiple dozers or managing rental equipment use this mount to move receivers between machines in seconds without tools or fabrication. One receiver can follow equipment across the job site, reducing capital investment and keeping operators productive.

Quick Job-to-Job Equipment Transitions

Site supervisors managing multiple work areas or daily equipment transitions install and remove the mount without downtime, keeping dozers on schedule and billable hours maximized. No welding, no fabrication delays—operators transition between jobs in minutes.

New Construction Site Grading

General contractors and site managers use the ATI-991364-02 during site prep and grade work to achieve accurate blade positioning and consistent finish grades. The fast-change capability allows mid-operation adjustments when grade conditions or site plans shift.

Heavy Excavation and Site Development

Excavation contractors use this mount for precision dozer work in cut-and-fill operations where blade control directly impacts final grades and material movement efficiency. The tool-free installation keeps equipment moving without site-based fabrication delays.

PRODUCT OVERVIEW

Product Description

The Topcon RL-200 2S dual slope grade laser package gives civil contractors, site developers, and grading crews a complete, field-ready system engineered for precision dual-axis slope work. This kit pairs the industry-proven RL-200 2S rotating laser with the LS-80X machine-control-ready receiver, a tenths-graduated grade rod, and an elevator tripod — everything needed to establish accurate grade planes straight out of the case. Whether you're establishing swales, matching existing drainage slopes, or executing decimal-dimensioned site plans, this package delivers the accuracy and setup speed professional crews demand.

System Overview & Jobsite Applications

The RL-200 2S sets dual independent slopes simultaneously on the X and Y axes, making it uniquely suited for parking lots, athletic fields, drainage channels, and ADA-compliant flatwork where two-axis grade control is essential. The LS-80X digital receiver provides audible and visual grade indication with a 1/16-inch detection window for fine-grade work and interfaces with most machine control systems. The tenths-graduated rod simplifies reading decimal elevations directly from engineer's plans, eliminating conversion errors in the field.

Job Applications

Parking Lot & Hardscape Grading: Program independent X and Y slopes to direct stormwater to inlets without re-leveling the instrument. The 2,600-foot diameter working range covers large commercial lots in a single setup.

Athletic Fields & Sports Turf: Achieve consistent cross-slopes and crown grades on football fields, soccer pitches, and baseball infields — applications where both axes must slope simultaneously and uniformly.

Drainage Channels & Swales: Set longitudinal and cross-slope in a single instrument position. The tenths rod lets crews read engineer-plan elevations directly without converting fractions.

Machine Control & Grade Checking: The LS-80X receiver mounts to motor graders, scrapers, and excavators for automated blade control, then doubles as a handheld checker for final grade verification.

Frequently Asked Questions

Can the RL-200 2S set different slopes on both axes at the same time?: Yes. The RL-200 2S is a true dual-slope instrument, allowing you to independently program a slope value on the X-axis and a separate slope value on the Y-axis simultaneously — no need to re-level or reposition the instrument between axis adjustments.
Why does this kit include a tenths rod instead of a standard 8ths rod?: Civil engineering and site development plans are typically drawn in decimal feet. A tenths-graduated rod lets your crew read 0.1-foot increments directly from the rod face, matching your plan dimensions exactly and eliminating the math errors that come with converting fractions to decimals in the field.
What is the advantage of an elevator tripod in a laser kit?: An elevator tripod has a center column that raises and lowers independently of the tripod legs. This lets you quickly adjust instrument height to clear obstacles, match a required benchmark elevation, or reposition for different crew needs without having to re-level the tripod from scratch each time.
Is the LS-80X receiver included in this package compatible with excavator or motor grader machine control systems?: The LS-80X is designed with machine control compatibility in mind and can interface with most popular aftermarket and OEM grade control systems via its mast-mount bracket. Always verify pin-out and signal compatibility with your specific machine control brand before installation.

What's In The Box

Apache Bullseye Magnetic Mount

Why Buy This?

Continuous grade control. No continuous labor.

Grade stakers cost $50–80/hr and disappear between passes. A dual-slope grade laser installs once and controls your blade automatically — through every cut, every fill, every pass. That's the math that makes grade lasers one of the fastest ROI investments in earthwork.

Professional contractors specify dual-grade systems for a reason: single-grade units work for straight drainage. The moment a job has a crown, a swale, or a complex parking lot slope — you need dual-grade.

Buying from Express Tools means authorized, factory-fresh inventory, legitimate firmware, and technical knowledge when you need it.
