Top sash guide for pacific windows corporation.

5/8" wide x 1.75" long x 0.75" from screw to holding lip

Need help ordering replacement part. Multiple guides have broken lips and several windows in the house fall down and do not stay open.

Thank you.

Your top sash guide isn't made anymore, but you should be able to use our 18-171 as a replacement. You'll have to trim down its top so that it can fit under your sash cap, though. I'm sorry that we couldn't offer you a better match.

Thank you, Tom. Why wouldn't the 18-008 work?

The shaping of the 18-008 is different than yours, the hole placements of the 18-008 doesn't match up with yours, nor do the measurements. Our 18-171 is the closest match we have to your part.
