looking for these fasteners to hold storm windows in place

Harvey Building Products put supplied and installed my windows in 2006. it was part of an airport project in my area for noise abatement. I live near a busy airport. I was given your company name by Harvey, to possibly be a source to get replacement parts. they no longer in the window business. I have attached the pictures of the parts that hold the storms in place. Over the years of taking them in & out some pieces have gone missing.

Please respond with a yay or nay as whether or not I can purchase these parts through your company.

Thank you

Rose

Hi, Rose.

I'd say this is a possible "YAY". The style of your hardware resembles our 70-050 and 70-050B but I don't know your dimensions so I can't be 100% sure either of these will work. They are our best options, though. Review the dimensions for each and compare them to yours to see if one of these matches up to your old fastener.
