Wile replacing broken channel balances the left top Sash Guide broke.
Would like confirmation that your PN# 18-188 will fit. Photos are the same part from other side. Window is Milgard circa 1999.
The only dimension that looks a bit off is the sideview where your drawing calls out 9/32". Mine appears to be 11/32". I suspect it will work but not sure.

We've seen this Top Sash Guide come up a few times. We don't have an exact replacement, but the 18-188, 18-009 and 18-166 are the options we usually recommend trying. We've never heard back from a customer about which of these would work, but I recommend going over the dimensions of each and try using which matches best. Let us know what you find.

Bob - Thought you would like to know that your part #18-188 arrived today. I replaced both sash guides and they work just fine even though the dimensions are not quite identical to the originals (as noted earlier).

Great web site and great support! Thanks for the help. I'll be recommending Swisco to all I know who are doing home repairs!
