FEMALE MAINSPRING KEY for YOUR Park-O-Meter, Rockwell POM Parking Meter, NEW!

Description

Up for auction,
Is a square female mainspring winding key (mainspring key fits the mechanical
coin/clock mechanism with the SQUARE POST ONLY!).
If you have a mechanism with a square hole, I offer a male mainspring key in a different listing. (see my other auctions).... If your coin/clock mechanism has a "Torx like" post, I can not help you with that style of key.   Please see additional pictures to make sure that this key is correct for your meter. I have a very large selection of Drive-In Speaker and Parking Meter parts, please let me know what you might be looking for and I will get it listed for you!
"Wolf Enterprises is a full line parts distributor for both Duncan and Park-O-Meter parking meters"
Again, you are bidding on the KEY in the 1st Picture! PLEASE make sure that this is the correct style of key for your parking meter.
Please let me know if you have any questions!
Due to a Shoulder problem... and I only have part-time help in the shop, twice a week. I have changed my handling time from 1 day to 5 days. This will be in effect until my shoulder gets better. Thank you for your understanding! Roger
