You would need to remove your roller to determine the correct match, which very well may require removing part of the bottom frame if no installation screws are visible. If you're not comfortable taking on such a project, you may want to consider enlisting the help of a local professional. In the meantime, take a look at the 81-133 roller. The roller part shown in your photos is a similar style but you'll need to remove the rest to confirm if it matches the specifications below. Look over the related information and video as well. Thank you. Alternate image for 81-133
