Abstract
A measuring device that has an upper guide movably engaged with a lower guide. The upper guide is extendable relative to the lower guide in a first direction along a first axis, and retractable relative to the lower guide in a second direction along the first axis. The upper guide and lower guide form a straightedge that is adjustable. The measuring device includes one or more rulers and levels. A locking mechanism operatively engages with the upper guide and lower guide. The locking mechanism is configured to lock and maintain a position of the upper guide relative to the lower guide and unlock to allow extension and retraction of the upper guide relative to the lower guide. The units of rulers on the upper guide can increase along the second direction, and the units of the rulers on the lower guide can increase along the first direction.
