4' x 4' Magnetic Polar Coordinate Whiteboards. There are (12) twelve concentric circles on 1 7/8" centers. Lines to circumference are 15" apart. The outside diameter of the polar graph is 45".
The 4' x 4' polar coordinate boards are a porcelain steel, magnetic receptive unit with a dry erase writing surface. The lines are fused into the writing surface to last a life-time. The trim is 1" satin anodized aluminum and there is a full-length 2 3/4" deep aluminum marker tray on each unit.
Each polar coordinate board ships with a set of 4 assorted markers, an eraser and the installation hardware. Sorry but the 4x4 polar coordinate boards are too large to ship by UPS so they must ship by truck.
50-year warranty on the writing surface. This is a 24 gauge porcelain enameled steel
surface on 1/2" fiberboard with a 92 gauge Mylar backing. The steel surface makes the board magnetic receptive. The graphics are permanently fused with the porcelain steel surface
4' x 4' Magnetic Markerboard with Polar Coordinates and 1" Map Railing Comes with a 1" factory installed map railing at the top of the board. Full-length chalktrays are standard on all boards.
