Letter Box Mail Catcher Metal Basket Wooden Doors Only

It looks good and is easy to install but the post seems to be getting a bit mashed

Basically a good product, good value, easy to assemble and attach to the door. However the dimensions given are only for the size at the door, which I measured, allowing 2cms clearance yet it narrows a lot in front so my internal letter box flap would be stopped from opening if I used it. I sold it to neighbours with a smaller letter box at a loss and they are happy with it. Please give full dimensions info in future.

Love it so easy pick up my post without giving me a bad back hahaha
