Measuring Laser Unit LM320F by Unit — 4x 90° lines, Li‑ion battery, three‑plane lasers, magnetic mount

Unit LM320F is a measuring laser designed for alignment and leveling tasks in interior installation and construction. The device projects four 90° lines across three planes to provide horizontal, vertical and cross-line references. Powered by an integrated Li‑ion rechargeable battery and equipped with magnetic mounts, the LM320F attaches to metal surfaces and supports continuous use on tiling, framing and general alignment jobs.

Advantages

The LM320F produces four precise 90° lines across three planes to simplify layout and plumb work without manual marking. The built‑in Li‑ion battery delivers long runtime and quick recharge capability, reducing interruptions on the job. Magnetic mounts allow secure attachment to steel studs and metal profiles while freeing hands for measurement and installation tasks. Compact housing and clear beam projection make the unit suitable for confined interior spaces and repetitive alignment operations.

Suitable for

• Wall and floor tiling alignment
• Door and window framing
• Suspended ceiling layout
• Plumb and level checks during interior finishing
• General construction layout and site marking

Key specifications

• Laser plane configuration: four 90° lines across three planes
• Power source: rechargeable lithium‑ion battery
• Mounting: integrated magnetic mount for metal attachment
• Application environment: indoor use, construction and installation tasks
• Primary functions: layout, plumb and level projection

How to use

Place the LM320F on a stable surface or attach it to a metal profile using the magnetic mount. Power on the unit and allow the laser to stabilize, then align the projected lines with reference points on the work surface. Use the three‑plane projection to establish horizontal and vertical references and the 90° cross lines for squaring corners or laying out tiles. Recharge the Li‑ion battery as needed using the supplied charger and store the device in a dry environment when not in use.

Usage recommendations

For accurate results, verify the unit is positioned on a level surface or properly fixed to a metal support. Avoid direct exposure of the laser beam to eyes and use appropriate protective measures. For prolonged projects, keep a charger accessible and periodically check beam visibility in bright conditions; consider supplementary marking tools when ambient light reduces line contrast.
