bottom sill guide

Hello,

We'd be happy to help but I'm not sure which sill guide that you're referring to. Is there a particular product code that you found on our website? If you are looking for a replacement for your guide, we would need to start by seeing pictures of your part to compare to our inventory. Thank you! 

Thanks for getting back to us. The height differs slightly depending on the section of the part that you're measuring but the tallest position measures just shy of 9/16" and about 5/8" if you include the small peg on the bottom. Just let us know if you have any other questions.
