Through-the-wall mail slots
How a through-the-wall slot works
- Mail goes in through the drop door on the outside faceplate.
- It slides down a chute angled through the wall. The Through the Wall Letter Drop Slot fits walls up to 5-3/4 in, or 12 in with its chute extension.
- Inside, it drops into your home or a locking receptacle.
