STABILAs magnetic Jamber Sets are bestselling level sets that include 32 inch type 96 M levels and 78 inch type 196 M levels. Among other things, magnetic Jamber Sets are great for installing doors. The recessed magnets on the 78 type 196 M levels align directly with hinge patterns on many residential and commercial doors. STABILAs type 96 M and 196 M spirit levels feature extra-rigid rectangular box beam aluminum profiles with reinforcing ribs, milled and covered measuring surfaces, removable shock-absorbing end caps with anti-slip wall grips, and very accurate matched vials that ensure all plumb readings are the same when leveling in normal and reverse positions. These hand tools are the most popular STABILA box frame spirit level tools in North America! Level sets are cost effective alternatives for those seeking to acquire multiple STABILA spirit levels.
