The level is a ProMaster ribbed box beam high profile, heavy-duty structure, with all four corners reinforced by additional internal ribs, and a large center hand grip for easy carrying, powder coated brilliant fluorescent yellow. Advantage: Superior strength, warp proof, easy to clean, and easy to hold. The vials are solid acrylic mechanically locked to the level body. They feature large bubbles, easy to read, fade resistant, and leak proof vials. The vials will never fog and are virtually unbreakable. Advantage: Mechanically fixed vials may be replaced by the user should a vial be accidentally broken. The extension rails have dovetailed designed ribs that match the ribs on the level. This allows you to lock them in place at any extended position accurately. They are designed to slide on the outside of the level and are open to allow for cleaning of the tracks. Advantage: Open design allows for cleaning of the ribs offering continued smooth operation and the ability to file clean any dents should damage accidentally occur. Use the system with one rail on each side of level, or use both rails on same side. This gives the user a straight edge on one side to check for warps in your the material, and a ¾’’ stand off on the opposite side to bridge any warps, allowing you to plumb from plate to plate. The user may also remove the rails and use the level by itself. Advantage: Versatility, this level system allows the user to have one tool that is high quality and easy to use, for fast and accurate wall installations. The user has the ability to change the rails, to use as a straight edge on one side and with a stand off on the other side, and be extendable to the length required, allowing accurate plate to plate plumbing of walls. Then be able to use as a standard level without the rails.
