No more eyeballing -- set up a true vertical line, any time, anywhere, without batteries. This plumb bob kit from Longacre includes two heavy bobs with a high-visibility yellow string. Simply tie the string to the bob and hang the string from any solid object. The bob will pull the string tight, indicating a line perfectly perpendicular to the ground.
Use them to align your suspension (find the chassis centerline or measure camber), apply graphics, measure angles, set up canopies, or even find out if your engine hoist is positioned where it needs to be.
