Westward 4MRV5 Magnetic Box Beam Level 24" hand tool

24" Magnetic Box Beam Level

The Westward 4MRV5 is a 24 inch magnetic box beam level designed for tradespeople and serious DIY users who need reliable alignment on metal framing or piping. Its magnetic strip holds the tool firmly to ferrous surfaces so both hands stay free for marking or fastening. Three acrylic vials provide plumb and level references in one compact tool.

Accuracy limits for general layout

The level is rated to an accuracy of .001 inch, which suits typical carpentry, drywall and mechanical installation tasks. The solid acrylic barrel vials resist fogging and impact better than glass, but the tool is not calibrated for precision machining or surveying work that demands tighter tolerances. Magnetic adhesion varies with surface thickness, coating and cleanliness, so verify holding force on the actual workpiece before relying on it.

Check your application before ordering

Confirm that a 24 inch length fits the span you regularly measure and that the three-vial layout matches the readings you need. The magnetic base only engages ferrous metals, so non-magnetic materials such as aluminium, copper or stainless steel will require clamping or manual support. Buyers who need longer reach, electronic read-out or non-magnetic operation should look for a different style of level.
