24" Magnetic Box Beam Level

The Westward 4MRW6 is a 24-inch magnetic box beam level built for tradespeople who need reliable alignment on metal surfaces. Its aluminum frame holds three acrylic barrel vials, including one level and two plumb vials, with a standard accuracy of .001. A single magnetic strip and two V-grooves allow secure placement on pipe or ferrous stock.

Hands-free metal work, not non-magnetic surfaces

This tool suits electricians, plumbers and metal fabricators who want the level to stay in position while they mark or fasten. The magnetic strip frees both hands on steel beams, conduit or ductwork. Buyers who primarily work on wood, concrete or aluminum without ferrous backing will not benefit from the magnetic feature and should consider a non-magnetic alternative.

.001 standard accuracy

The stated accuracy of .001 is the single specification that determines whether this level meets the precision demands of your layout work. If your trade requires tighter tolerances, this model will not satisfy those requirements. If the tolerance is acceptable, the magnetic strip and three-vial layout make it a practical choice for 24-inch spans.

Questions about this item

Will the 24 in aluminum frame with its single strip magnet fit on standard steel studs and I-beams?

Yes, the 24 in aluminum box beam has one magnetic strip that holds the level to ferrous surfaces such as steel studs and I-beams for hands-free use.

How do I mount this level so the vials stay accurate, and what is the common mistake?

Place the level on the work surface, let the single strip magnet engage the metal, then read the one level vial and two plumb vials; the common mistake is applying side pressure that bows the 24 in frame and throws off the 0.001 in accuracy.

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

Wipe the three acrylic barrel vials and the aluminum frame with a damp cloth to keep the fluid clear; check the single magnet strip for metal filings that reduce grip, and replace the level if any vial bubble drifts from center.
