This is in a 2 year old Champion manufactured home. We purchased it new 1 year ago new from the dealer. The reason I provided this information is I read you recommend replacing in sets of two (both sides). We have only opened the window a very few times so I didn't know if you would still recommend replacing both sides.
I think the pictures provide the necessary information.
My concern is the thickness being just shy of 9/16".

Hello! Your shoes and casing look to be in good conditions. Could you get away with just replacing the spring? If so, I recommend our Series 180. This should work well for your existing balance system. |
