Aluminium Box Section Straight Edge – Refina Heavy Duty Levelling Rule

The Refina aluminium box section straight edge is a precision levelling tool designed for flooring, screeding, wall levelling and general building applications, where accuracy and straightness are essential.

Manufactured by Refina using precision-grade aluminium extrusions, these box rules are built for heavy duty site use while remaining lightweight and easy to handle. They are commonly used to identify high and low spots, check surface regularity, and ensure materials are laid flat and level across walls and floors.

The rigid box section profile provides excellent straightness over longer spans, making it ideal for floor levelling, screed preparation, plastering and rendering work. Clean, burr-free edges allow the straight edge to glide smoothly over surfaces without dragging or marking materials.

Available in a wide range of lengths, these straight edges suit everything from detail levelling to large floor areas and long wall runs.
