Channel sash

Question

Which channel sash do I need to replace the one pictured. I am torn between the 370 and 385. My sash measures 12" in length and 5/8 depth and width. The bottom piece is just over an inch in depth and has what appears to be wings. No wings on the top piece. My current sash is stamped 1220. Thank you in advance.

Hello!

It looks like your top fitting is non-winged, while your bottom fitting is winged which leads me to recommend our S350-13. Compare the specifications and see what you think. You will also need to select the 1220 strength option based on your stamp.

Your metal channel should measure as 13" long so you'll want to double check this measurement before proceeding. Make sure to only measure the metal channel and don't include the plastic fittings in this measurement!
