Sliding patio door rollers

Hello,

Your roller is a similar design to the 81-049. With that being said, our dimensions differ slightly from the ones you've provided. I would recommend double-checking the housing height to see if it might be 1-3/16". The housing length is not normally a deal breaker since the bottom of the door is generally open to compensate for the difference. As for the wheel diameter, you may be able to adjust our roller to sit lower in the door to make up for the size difference but we also offer the 1-1/4" diameter 81-266 roller and axle kit if you need to swap out the wheels. Look over these parts to see if they could work for your repair. Thanks for posting!
