I'm afraid we cannot replace this exact operator, as it is very old. However, you may be able to adapt our 39-027E and 39-028E to your window, along with a new track like our 39-533. I cannot guarantee these will work, and if they do they you may need to adapt your sill trim to get these to fit, but we do not have anything closer. |
