Product may have been opened for inspection. Never used.This is a -36 unit meaning it is meant for Acu-Rite devices where the maximum measuring range is 36 inches. Acu-Rite bases their scale sizes on reading length, not overall length. Therefore, the physical dimensions of the scale and the backup spar will be greater than the measuring length. We measured the overall length, and it is 42 1/4 inches.
The package includes the backup spar hardware kit 680228-04.
