Box levels are a fundamental part of any professional builder's toolkit, as they play a vital role in confirming horizontal and vertical straightness and are harder-wearing than some alternatives. As best practice is to use the largest boxing level that can fit on the surface that you're checking, our boxing levels are available in many different sizes, from 600mm to 2,400mm. In our range, you'll find the 650 Series compact box level, designed for users who want a lightweight, durable way to measure for straightness that doesn't compromise on accuracy. A quality aluminium frame provides great durability, while hybrid sub-flush plumb vials are similarly hardy, resisting breakage, leaking and fogging. Its visibility is great, too, thanks to an impact-resistant 300° viewing block that lets you take a reading from any number of positions. The 550 series box level is also extremely lightweight, while delivering an impressive 0.5mm/m accuracy, using three electronically calibrated acrylic block vials. The vials have a lifetime warranty and the liquid inside them is UV-protected, so you and your employees won't have to worry about finding replacements any time soon. Alternatively, why not stock up on the E875 & em76 Series True Blue® box levels? The True Blue® brand is synonymous with strength, accuracy and superior visibility. You won't be disappointed by the precision of these box beam levels, as they can get a reading that's accurate to 0.5mm/m in 10 working positions. This is enhanced with the help of an Empire®-exclusive reinforced vial locking system that protects acrylic block vials' reliability. What's more, these levels work a treat in poor lighting conditions, due to high contrast e-BAND™ vials that highlight the edge of the bubble for you. After spending over 100 years developing long-lasting measurement tools upon which construction professionals all over the world now rely, you can trust Empire® to help you to deliver the results that you need.
