Roller Assembly needed for wooden patio door

Question

When my home was built in 1978 or 79 a Pella sliding glass door was installed leading to the deck. The door is wooden construction but has no metal cladding. After careful inspection I have been unable to find a model or serial number on the door. One of the roller assemblies has failed making the door rather difficult to open and close. Thus, I am hopeful that you can tell me what door model or models were in use at the time our home was constructed.

If I can provide you with any additional information which will make identification of the door model easier, please let me know. Thank you.

The only way to determine which roller you need is to remove your existing one from the door. I think it could be either the 81-249 generic roller or the genuine Pella 81-098 roller. These are for the older Pella doors. We also carry the 81-244 for the newer style doors. However I'm not sure which one of these will fit your door. That's about as far as I can narrow it down without seeing the original out of the door.
