Patio Door Rollers

Hey Michael. This reminds me of our 81-148. Please compare to the diagram below and let me know if this matches up.

Hello again! The height is very important, yes. Even a difference of 1/16" might be a dealbreaker. I would suggest double checking that particular dimension just to be safe. We unfortunately don't have a version of this roller with a 1-3/16" height, so if that is how tall yours is then it may not be something we can supply.

As for cost, you can see a full price breakdown on the 81-148 store page. Shipping is calculated for you automatically during checkout and will be dependent on what delivery option you select.

Lastly, the back screw does control the adjustment, yes.

Unfortunately I'm not aware of a tandem version of the 81-148. I can only tell you with confidence that we don't sell anything that would match that description. I'm sorry for the inconvenience.

As for adjustment, you want the wheel to be adjusted up as far as it can go into the housing during installation. This will give you more than enough clearance to put the door back in the track. After that, the proper adjustment height is something you'll have to judge as you do it. The goal is to ensure that the door doesn't rub against the bottom track and threshold, nor against the top header.
