⚡ At a Glance
- • Accuracy: Accurate to 1mm/m thanks to a milled V-groove bottom face and clear spirit vials
- • Best for: Tradespeople and serious DIYers needing long, precise levels for pipework and large surfaces
- • Not ideal for: Tasks that require a short torpedo level or a digital angle readout
Powder-coated extruded aluminium construction gives a straight, durable rule for long measurements. UV-resistant 45°, 90° and 180° vials deliver easily readable lines for precise alignment.
Consistent, precise levelling – thanks to milled V-groove bottom and accurate vials
A milled V-groove along the bottom face seats round pipework and helps stabilise the level on curved surfaces, while three UV-resistant vials mark 45°, 90° and 180° readings. The assembly achieves stated accuracy of 1mm per metre through careful machining and vial placement.
Repeatable, trustworthy measurements make installations faster and reduce the need for re-checking during plumbing or cladding work.
Built for site use – with powder-coated extruded aluminium and protective end caps
Extruded aluminium at 1.1mm thickness maintains a straight edge without excessive weight, while powder coating resists surface wear. Protective end caps shield the ends from knocks and impacts common during transport and on-site handling.
Durable construction means the level keeps true under heavy use and survives everyday bumps and drops.
Easy handling and storage – with ribbed sides, hanging hole and long 1800mm span
Ribbed sides improve grip when carrying or aligning the level, and a built-in hanging hole allows tidy storage on site or in a workshop. The 1800mm span covers wide surfaces in a single run, reducing the need for joins.
Comfortable handling speeds up measuring tasks, while straightforward storage keeps the tool ready between jobs.
