sliding door rollers
Thanks for reaching out to us! Your sliding door roller appears to be missing its outer housing; this is likely still installed in the door. This part of the roller is important for identifying the exact replacement you need; we'll need see the shape and details of the housing. You'll also need to have it removed to accurately confirm the dimensions to ensure it will be a fit in the door.
I'm sorry to say we would not be able to identify the replacement you need based on the brand name of the wheel.
Take a look at the video tutorials I've tagged below for a demonstration on how to remove the rollers and what we look for to identify them.
