17" Series 751 Balance

A home owner from North Dakota says:

Is the top clip included with this balance? If not, which clip do I need for the inner window?

I plan to install this balance on a Marvin window circa 1978. Measurements and photos seem to indicate this is the correct balance. What are your thoughts?

Are you referring to the "S" clip? If so, I'm afraid it is not included. You could have either the 19-029 short clip or the 19-030 long clip, depending on your length. Look them over and see which would be better.

Marvin has used many different kinds of balances, so I can't confirm if our Series 751 is what you have. However if our pictures and measurements all match up to what you have installed now, there's a good chance you're on the money.
