48-Inch Magnetic Box Beam Level

The Westward 4MRV4 is a 48-inch magnetic box beam level designed for professionals and serious DIYers who need precise alignment over long spans. Its extended length suits framing, carpentry and metal fabrication tasks where accuracy across wide workpieces is essential.

Box Beam Construction With Magnetic Strip

A rigid box beam profile resists twisting and holds three vials rated to .001 inch accuracy. An integrated magnetic strip secures the level to ferrous surfaces, freeing both hands for marking or fastening while the tool stays firmly in place.

Top-Read Vials And Surface Compatibility

Top-read vials allow clear visibility from above or below the workpiece, reducing eye strain in tight spaces. Verify that your primary work surfaces are ferrous if you plan to rely on magnetic attachment, and confirm the 48-inch length fits your typical material dimensions and storage area.

Questions about this item

What accuracy does the 0.001" spec deliver on a 48" level?

The 0.001 inch accuracy means the vial reads level within one thousandth of an inch over the full 48 inch length.

What mounting surface does the magnetic strip require?

The magnetic strip attaches securely to any ferrous metal surface such as steel beams or ductwork.

How do I install the level for a true reading and what step is often missed?

Place the level on the workpiece, wait for the bubble to settle in the centre of the vial, and confirm the same reading from the top-read window before marking.
