A sprinkler drop ruler is provided for measuring the sprinkler drop from a roughed-in outlet. The sprinkler drop ruler includes a rigid frame having an opening, a handle connected to the rigid frame and in fixed relation to the rigid frame, and a ruler with an end shaped to seat in the opening and configured to move inside or along a side of the handle in order to measure a sprinkler drop. The sprinklerfitter may thus use the sprinkler drop ruler in order to measure the sprinkler drop. In this way, the sprinklerfitter does not need to climb a ladder to measure the sprinkler drop. |
