Abstract
An improved vertical lift door roller assembly has a wheel pivotally mounted to a shaft. The shaft is placed within a spring loaded locking cylinder. The locking cylinder is movable between a first position where it restricts pivoting of the wheel and a second position where the wheel is able to pivot. When the door roller assembly is used on a vertical lift door, the wheel can be pivoted to decouple the roller from a vertical lift door J channel wheel track.
