The standard patio door rollers (we often order from CR Laurence) are the same except for the position of the side tabs. These are lowered so the bottom of the tab is level with the bottom of the wheels (NOT the housing). The standard tab placement does not allow enough clearance to get the wheels back into the track once installed.

Please take a look at our 81-018 sliding patio glass door roller and let us know what you think. Could this be used in your patio door? Let us know.
