Topcon RL-H5A Self-Leveling Laser PS.DB 1021200-49-K1 with LS-80X Receiver, Measuring Rod 10ths and Tripod - RECHARGEABLE

Field-Ready Rotary Laser Performance at a Practical Price Point

The Topcon RL-H5A DB2 Rotary Laser Kit (1021200-49-K1) gives site contractors and concrete crews a reliable, no-compromise leveling solution without paying for features you'll never use in the field. Backed by Topcon's decades of precision instrument manufacturing, the RL-H5A is built to handle the day-to-day rigors of grading, footing layout, drainage work, and interior leveling across a 1,000-foot diameter working range. This complete kit ships ready to work — unbox it on the jobsite and you're measuring within minutes.

Package Overview & Jobsite Applications

The 1021200-49-K1 bundle pairs the RL-H5A laser head with Topcon's LS-80X digital receiver, a heavy-duty aluminum tripod, a tenths-graduated grade rod, and a rechargeable battery set. Whether you're checking subgrade elevation across a large slab pour, setting batter boards for a foundation, or establishing finished floor height inside a structure, this kit covers the fundamental leveling tasks that drive productivity on commercial and residential job sites alike.

Job Applications

Concrete Flatwork & Slabs: Set the RL-H5A at a central point and sweep a full 360° reference plane across your entire pour area. The LS-80X receiver clips to a grade rod and gives your crew audible and visual cut/fill guidance without line-of-sight dependence on a single person.

Site Grading & Drainage: Establish consistent subgrade elevations across a pad or verify positive drainage slopes. The 1,000 ft working diameter means one instrument setup covers most residential and light commercial grading operations.

Foundation & Footing Layout: Use the kit to set batter boards at consistent elevation before excavation, and verify footing form heights before the pour — critical steps that prevent costly elevation errors downstream.

Interior Finish Work: Suspended ceiling grids, floor leveling compounds, and partition framing all benefit from a horizontal reference plane. The RL-H5A's compact form and quick self-leveling make it equally capable indoors and out.

Frequently Asked Questions

Does the RL-H5A work for grading slopes, or is it horizontal-only?

The standard RL-H5A is a horizontal self-leveling laser. It does not project a user-defined grade plane. For slope or dual-grade work, look at the Topcon RL-H5B or a grade laser model. For most flatwork, foundations, and interior leveling the RL-H5A is the right tool.

What is the maximum range of the LS-80X receiver included in this kit?

The LS-80X receiver extends the working diameter to 1,000 feet under good lighting conditions. In bright direct sunlight, outdoor range may be reduced; use the receiver's sunshade and ensure it is pointed toward the rotating laser head for best signal acquisition.

Can I use the RL-H5A indoors without the receiver?

Yes. Indoors and in shaded conditions you can read the visible laser beam directly on a wall or rod without the receiver, useful for ceiling grid and partition layout. The LS-80X receiver is essential for outdoor use where the beam is not visible to the naked eye.

Is this kit covered by a Topcon warranty?

Yes. As an authorized Topcon dealer, Express Tools sells the RL-H5A with the full Topcon manufacturer's warranty — one year on parts and labor. Topcon also offers calibration and repair services through their authorized service network.
