I am looking for replacement rollers for the above door type ddsg code tri-k-36. My door is hard to open and close.

I'm afraid we aren't able to identify replacement rollers based off of the manufacturer information, but rather only from seeing the rollers. If you can remove them from the doors and snap a photo, we're happy to help further.
