What can I use to replace this top sash guide? The lock on the window reads "ESP".

We'd like for you to start with taking a look at our 18-185 top sash guide. See if our measurements match up with yours. If this is in fact a match, it's only available in the natural plastic color. Should this part not be a match, let us know what the differences are. |
