Question: Does this really block drafts?  I am replacing an old mail slot that lets in the cold weather in winter.
Document: Item was well made, top quality.Had to improvise a little to get it to fit my 1931 door letter slot.Nothing any homeowner couldn't handle.I highly recommend this mail slot.
I purchased this mail slot to replace an ancient tarnished one. Unfortunately, this odd-sized replacement is slightly narrower than the older standard size one (12") and I had to improvise when one of the screws was unable to attach to wood (because of the over-sized pre-cut opening in the door.) Otherwise, the quality is fine.
These things are small -- not big enough for a bundle of magazines. If you are replacing an older unit, make sure that the plate on the new unit is big enough -- otherwise you may have to improvise by making your own. Made of solid brass, but not quite like in the old days. Good enough though.
This was a beauty of an item. Looks great and works great. Glad I bought it.I don't have to worry about mail sticking out of my mailbox no more. I installedin my garage panel door and all my mail is delivered inside now. Thank you.
This is one of those rare times when you order something online and what you get is far better then you expect. This mail drop surround is solid brass, not plated, and carefully constructed. I received it 3 days from when I ordered it with standard shipping. Thank you Deerso and Amazon.
I ordered this for my mom to replace one that she already had. She gave me the number V1911 from National Hardware but I didn't realize that there were two sizes for this number. Unfortunately, I ordered the wrong size.
Unlike some of the other items examined, this one has an accurate description, necessary for replacement mounting. Price is reasonable, shipping was prompt.
Though not rocket science, It was a pain cutting through the wooden door, but looks great. Being brass it should last forever.
This was advertised as a yoga towel. Yet, it does not adhere well to my mat and slips all over during my practice. BEcuase teh towl is longer, there is actually more fabric to bunch and get in the way. Bad buy by me.
