Abstract
A sliding door roller apparatus includes a replaceable wheel assembly that can be easily removed and replaced on a holding member. The wheel assembly includes a resilient housing, a wheel, and an axle on which the wheel turns. The resilient housing has a pair of opposite facing sidewalls, each having an integral end portion that extends toward and overlaps the other. Each end portion includes at least one locking finger that is positionable within an opening on the holding member. The resiliency of the housing permits the locking fingers to be placed or removed from an opening located on the holding member. The apparatus also includes an adjustment mechanism that positions the wheel assembly outside the sliding door frame to permit the frame to be properly aligned within its door opening.
