Who knows Wipers and refills? Especially originals
Redfish. Thanks for explaining that. On mine I didn't bend the end metal, just slipped the refill end past the retainer end.
Measuring the current refill and the original retaining clips it's pretty obvious that the correct refill for a 15" push button should be just shy of 15". Approximately 14 7/8" or 14 and 15/16" I think. The width of the current refill's metal strip is roughly 0.360"
Based on the above, the dimensions in semi-current catalog suggests that none of Anco's is current refills will make a very good replacement.
Using info posted by some online retailers, I believe the correct refills for the 15" Push button blades were ANCO 680 and TRICO LP-15. Presumably the 16 blades were then LP-16.
Later Anco superceded the 680 with 12-15 and presumably the 16" versions were 12-16. I think I'm going to buy one of these old refills just to see what the dimensions are.
