Does this come in 16’ gray? How thick is this OR how does this compare to the similar looking ones on Amazon for half the price? Also how long would free shipping to 80906 be (est)?

The super seal only comes in black. It is 4 1/5" flat and 1 9/10" when installed on the bottom of a door. Our seal is American made in the midwest. The seals listed on Amazon are after market knock offs.
