I need rollers

Hello there. Based on that handle's design, it looks like you have a Pella door. The 81-244 is often seen with Pella patio doors, as is the 81-098 (we also carry a third-party version of the 81-098, see our 81-249). But I can't say which of these are what you need, if any. Unfortunately the only reliable way to identifying sliding glass door roller replacements is to remove the old ones and compare with possible replacements. Honestly, it's an exception that I can even narrow down your options to just a few possibilities, as I can with a Pella door. In other cases the hardware is so brand-independent that it's a complete shot in the dark without removing and comparing dimensions. See the videos below that detail how to remove and replace sliding glass door rollers, as well as how to identify their replacements. Let me know how you make out.
