ABSTRACT:
Disclosed is a truck span measuring apparatus adapted for positioning in the wheel well of a vehicle whose span is to be measured. The apparatus includes a housing having at least one female-threaded socket positioned on one end thereof. A male-threaded shaft is threadedly inserted into the socket and furthermore extends into the hollow interior of the housing. A pad-fitted end assembly is mounted on the free end of the shaft and is adapted to engage against the inner sidewall of a wheel well of a vehicle to be measured. The opposing end of the housing is also fitted with a pad-fitted bracket assembly which is adapted to engage against the interior sidewall of the housing of the wheel well. A collar assembly having a threaded bolt which extends threadedly therethrough, is mounted on the housing to slidable along the length of the housing. The threaded bolt is adapted to engage against the housing and provide a pressure-fit union for purposes of releasably securing the collar at a preselected location along the length of the housing. The collar is likewise fitted with a outwardly-extending shaft which is configured to receive and retain the bracket mounted on the free end of a measuring tape.
