These rollers are on 30 year old built rite sliding windows.

Question

Can you help identify replacements for them. Many are cracked on the plastic and the rollers themselves are quite worn.  They are 3/8" in diameter.

Thanks for your post! This sliding window roller appears to be a match for the 87-181 Tandem Roller Assembly. To confirm that this is the correct replacement, carefully look over the specifications and compare them.
