A robust level for demanding work. Rigid aluminium profile 24x50 mm (710g/m) with milled face on underside for maximum flatness. Large cylindrical level with magnifying effect for accurate and easy reading at any angle. Double graduation marks for easy reading at 2% drop. Made from impact resistant material with very good resistance to UV light. Vial radius of 200mm gives a sensitivity of 10mm/m, i.e. lifting the end 10mm on a 1 metre long level moves the bubble 2mm. Shock absorbing end caps with friction points to hold the level flat against a wall. Continuous hole for tool fall protection.
