Thanks for contacting SWISCO. I'm afraid I couldn't cross-reference that specific code with any particular operator cover we own--but there are just a few possibilities. If the spline is offset, it might be the 39-375 or 39-376. If it is center, check out the 39-107. Send us pictures of one of the operators if you are uncertain. And feel free to browse through our Window Operator Accessories page. |
