Cascade Window casing replacement

A home owner from San Diego says:


I am hoping that you can help. We bought Cascade Windows in 2012. We now have 13 of them that will not open or close. The casements are broken we believe and need to be replaced. I have attached photos so that you can hopefully understand which type of casement I should order.

I need these parts ASAP as I have a window tech coming to the house on Jan 18 to replace some compromised windows and I would like him to replace the casings on this same visit.

Thank you,

Hi Carolyn, thank you for posting,

I cannot see the base of the operator from the photos, but looking at the arms, I believe you have the 39-239B operator. Please review the dimensions on the product pagge to confirm a good fit. This operator uses the 39-536 pivot slide assembly to attach to the track. These parts are sold separately. 

Also review the 39-375 and 39-451 for a cover and handle depending on style preference. Please note that we do offer this operator in stainless steel, 39-239C.

Let us know what you think and if you have any additional questions!
