Aluminum I-Beam Level, 24 Inches

This Westward 4MRW5 level uses an aluminum I-beam frame that is 24 inches long. It carries three acrylic barrel vials: one for level, one for plumb, and one additional vial. The tool has no magnetic base, no top-read window and no vial illumination. Accuracy is rated at 0.001 inch per inch.

General layout and finishing work

The single level and single plumb vial suit carpenters, drywallers and DIYers who need to check horizontal and vertical alignment on site. Builders who require multiple level vials at 30 or 45 degrees, or a magnetic base for hands-free use on steel, should look at a different model.

Three-vial acrylic system

The three acrylic barrel vials provide the only reference surfaces on this level. Their 0.001 inch per inch accuracy determines whether the tool meets the tolerance required for the job.

Questions about this item

What length of material do I need to span so the 24 in level can sit fully supported?

The level is 24 in long, so the workpiece or surface must be at least that wide to keep the frame fully supported while you read the vials.

Will the acrylic barrel vials on this aluminum level scratch if I keep using my older steel rule against the same edge?

Acrylic vials are softer than steel, so dragging a steel rule across the level’s top edge can mark the vial windows; keep the rule clear of the vials to avoid scratches.

How do I confirm the level reads true after I set it on a surface?

Place the level on the surface, note the bubble position, rotate the level end-for-end on the same spot, and verify the bubble returns to the same position within the 0.001 in accuracy spec.
