A robust level for demanding work. Rigid aluminium profile 24x50 mm 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 200 mm gives a sensitivity of 10 mm/m, i.e. lifting the end 10 mm on a 1 metre long level moves the bubble 2 mm. Shock absorbing end caps with friction points to hold the level flat against a wall. Continuous hole for tool fall protection.
