Generally, sliding doors have a door panel that is supported within tracks in a head and/or still of a door frame by a roller assembly that enables the sliding door panel to slidingly open and close.

The roller assembly can include a pair of rollers that are adjustable within a housing so as to define how far the rollers extend out from the housing. By retracting the rollers relative to the housing, the sliding door panel may be more easily installed. Once inserted into the door frame, the rollers can be extended so as to set the position of the sliding door panel within the tracks. However, the retracted position of the rollers within the housing is difficult to maintain during installation because the roller assembly is not supporting the weight of the sliding door panel. As such, even when the rollers are retracted within the roller assembly, the rollers are known to often undesirably move towards an extended position during installation and/or removal of the sliding door panel from the door frame.

A sliding door roller for a sliding door includes a slide disposed within housing and a truck assembly disposed within the slide. When the truck assembly is retracted within the slide, the truck assembly and the slide are at least partially engaged to as to restrict or prevent the truck assembly from dropping out of the housing and rotating within the housing. The truck assembly being disengaged from the slide via an adjustment fastener to move the truck assembly towards and extended position relative to the housing.
