Parts for Guardian patio door

We don't sell this exact handle set, but I think our 82-030 would be a good fit. It has a 3-15/16" hole center spacing and should be fully compatible with your existing mortise.

Hi, 

Tom, is out today but I'd be happy to answer your questions. The 82-030 that Tom mentioned is compatible with the 82-310 key lock. Take a look at our guide for these parts here. 

As for your roller, we may very well carry a replacement but we would need to see the original roller removed from the door to compare to our inventory. Thank you!

I'm afraid I don't know what you have. Guardian only makes glass, they don't make doors.

Before I make a recommendation, can you show me a photo of the handle in question? Can you also verify the hole spacing? Make sure to only measure from the center of each hole, not their edges. It should be more like 3-15/16".
