## Questions & Answers

**Q: The opening of my mailbox is 7 9/16" wide and 9 9/16" tall. Do you have a size that will work for these dimensions? If so, what size?**
A: Good morning.    Based upon the dimensions you have listed for the opening, if your mailbox is a metal mailbox, our 8"x10" should fit well.    If for any reason it will not, we will gladly refund your order.

**Q: Does this product include a replacement insert or just a door? The photos seem to infer there is also an insert...**
A: The RetroFit secures into place with an insert which has wings that compress as inserted and snaps into place behind the natural ridge at the front of the mailbox canister.  You will see this insert, which is attached to the door in the photos   The insert extends only a couple inches into the mailbox

**Q: my mailbox is 8" x 10 1/2".  Will this door work on it?**
A: If that is the opening dimensions I'm afraid your height would be too tall. Our doors only work on metal mailboxes, and ones that the opening is 8" wide and 10" in height. We do not use the measurements of the door itself.

**Q: Busco una tapa de 14 pulgadas de altura y 11 de acho**
A: This door would not fit your. mailbox, you would need to look for our Jumbo 11" x 14" RetroFit mailbox door.
