pile replacement

A quick learner from california says:
I have 70s-era sliding windows (aluminum) that have worn piling. I'll attach photos. The base of the pile appears to be 1/4 inch. Can't tell the height because the pile is so worn down.

I'm not sure what you have either. Without knowing more precise measurements, it's very hard to identify the correct pile. You could start by looking at our 58-045 and 58-128, but I can't say for sure if these will work.
