Abstract: A pop-in extended travel single roller for patio doors is retained in the patio door track by no mechanical device. This is accomplished by mounting the roller assembly into a pre-fabricated opening, the width of which is slightly larger than the over-all basic width of the outer housing. Protrusions on the side of the outer housing, after passing through the opening, retain the roller in the proper position. This feature eliminates the need for mechanical fasteners thereby saving costs of parts and labor. This assembly also provides for increased over-all height adjustment range aids the ease of removal of the movable panel of the patio door assembly through the use of an adjusting screw.
