I'm unable to find the part number to order this item. I ordered the corresponding channel balance (27" Series 380 Channel Balance S380-27 option: 2640)and it worked perfectly. However the plastic stopper on one window is broken.
Please let me know the item number so I can order replacements.
Thank you.
Linda

Hello, Linda. I recommend looking at our 18-188. This looks like it could be a good match but see what you think.
