Milwaukee Electric Tool EXT40 Extendable Box Level 24-40 in

Product Description

The Milwaukee Electric Tool Corp EXT40 is an extendable box level designed for layout and leveling tasks across a wide range of trades. The EXT40 adjusts from 24 inches to 40 inches, allowing a single tool to cover multiple measuring lengths without swapping between fixed-length levels. The True Blue vial system is built for high-visibility readability in varied lighting conditions. This level is suited for use by carpenters, plumbers, HVAC installers, electricians, and general contractors who need a reliable, adjustable leveling tool on the job site.

The EXT40 is appropriate for residential and light commercial applications where level and plumb readings are required during framing, fixture installation, equipment mounting, and rough-in work. Its extendable design makes it practical for tasks where a standard 24-inch level falls short but a full 48-inch level is unwieldy. It fits naturally into a general tool kit for any trade professional performing installation work.

Key Features

• Adjustable length from 24 inches to 40 inches for versatile on-site use
• True Blue vial system for clear, accurate level and plumb readings
• Box-beam construction provides structural rigidity across the full extension range
• Single tool replaces the need for multiple fixed-length levels in many common applications
• Designed for trade professionals working in residential and light commercial settings

Compatibility

Designed as an OEM-style replacement or direct addition for professional tool kits requiring an extendable box level in the 24-inch to 40-inch range.

Installation Notes

No power source or lockout procedure is required for use of this level. Ensure the extension mechanism is fully locked before taking a reading to maintain accuracy. Clean vial faces and reference surfaces before use to avoid false readings. Periodic calibration checks against a known reference surface are recommended for continued accuracy.
