Stanley FatMax I-Beam Μαγνητικό Αλφάδι 200 cm 1-43-558

On a busy construction site, a carpenter checks the alignment of a long wall, relying on a level that stays firmly in place on metal studs. The Stanley FatMax I-Beam Magnetic Spirit Level 200 cm (1-43-558) is built for such demanding tasks, combining a robust I-beam profile with powerful rare-earth magnets. Its 200 cm length spans wide surfaces, while the three block vials—horizontal, vertical, and 45-degree—ensure precise readings in any orientation. The high-grade aluminum body resists bending, and shock-absorbing end caps protect against drops. Bi-material hand grips provide a secure, comfortable hold, even with gloves. This level is a dependable tool for professionals and serious DIYers who need accuracy and durability on the job.

Good to know

The level is 200 cm long, making it suitable for wide spans but may be cumbersome in tight spaces. The magnets are strong but work only on ferrous metals; for non-magnetic surfaces, use the level as a standard spirit level. The block vials are highly visible and resistant to leakage, ensuring long-term reliability. No batteries or electronics are required—it's a purely mechanical tool that works in any temperature. A storage case is not included, so consider a protective sleeve or bag for transport.
