Greetings. This actually reminds me more of the upper half of our 18-159P Top Sash Guide pair. Compare the dimensions and see if you think this pair is what you need. |

I have even better news than measurements. It turns out we recently brought in a version of this guide that's just the top half, that looks much closer to what you have. See our 18-204. Note that the hole spacing measurement is included in the pictures. |
