This level from Draper has a highly visible red Opti-vision TM tilted vial which allows a single bubble view over 90° and a front view thanks to the Plumb Site® Dual View TM RedEffect TM vial. The aluminium box section extrusion has a milled base (not 1800mm), curved top, and is electrostatically powder coated and baked with polyester acrylic paint. The Ergo Grip TM , nonslip, soft grip handles, tough bi-material end caps, anti-slip wall pads and vertical vials make for comfortable usage during longer jobs.
