tandem rollers for a Pella patio door

A handy person from california says:
need to replace tandem roller for a Pella vinyl sliding glass (dual pane) door. Pella part number is V782874 for the stainless steel and V782875 for the standard metal rollers. The number on the door itself is: P21 IG-3 Oct 26 2004 618287 01 4.

Does Swisco.com part number 81-030 work as a replacement or is there another part that I should order? Do you carry a replacement part in stainless steel? The size of the current adjustable tandem roller assembly is: 11/16 wide, 3 1/16" long and 1' high excluding the wheels that are 1 1/4 in diameter.

Thanks for contacting us! Are you sure you have a Pella brand door? I do not believe that the 81-030 Acorn Patio Sliding Glass Door Roller can be used for Pella doors. Could I perhaps see a few pictures of your existing roller? Make sure that it's fully removed from the door before you take the pictures.

don't have camera available. I'm sure I have a Pella doors, and I have provide you with the dimensions of the current roller assembly which needs to be replaced.

The 81-030 Acorn Patio Sliding Glass Door Roller does appear to be close, but I agree with Tom. Seeing what your original roller looks like would be the only way we can be certain.

Sometimes there are subtle differences in the way these rollers are manufactured that diagrams and dimensions can't really show. Seeing your roller would be a great help in finding the best possible replacement for you.
