Patriot sliding glass door roller

Hello,

Past customers with Patriot patio doors have used the 81-156 roller assembly. With that being said, we can't be sure if that is what you have without seeing the original roller uninstalled. Take a look and compare the specifications below to your part. If you notice any discrepancies, please get back to us with additional photos and written-out dimensions to research this further for you. Thank you!
