24 Inch Magnetic I-Beam Level

The Westward 4MRW1 is a 24 inch magnetic I-beam level designed for tradespeople and DIY users who need reliable horizontal and vertical alignment on ferrous surfaces. Its magnetic base allows hands-free positioning on steel studs, beams or pipework.

Three vials with 0.001 accuracy

Three vials provide plumb and level references with a stated accuracy of 0.001. The blue and black colour scheme improves vial visibility against common job-site backgrounds during normal use.

Hands-free steel work and toolbox storage

Magnetic attachment frees both hands for marking or fastening while the level holds itself in place on metal framing. The 24 inch length fits standard toolboxes and suits layout tasks where a compact straight edge is required.

Questions about this item

How do I attach the 24" magnetic I-beam level to steel studs and what step is often missed?

Press the magnetic edge firmly against clean ferrous metal so the full length contacts the surface; the step often missed is verifying both plumb vials and all three leveling vials read true before marking.

What upkeep will the three acrylic vials and magnetic edge need over time?

Wipe the vial faces and magnetic strip with a dry cloth after each use; avoid solvents that can cloud the fluid and keep the edge free of metal filings to maintain holding force.

At what point does the .001 accuracy spec become unreliable during extended layout work?

Accuracy can drift if the aluminum I-beam warps from heavy drops or prolonged heat exposure, so re-check against a known reference after any impact or temperature extreme.
