Which is the correct replacement product for the wood exterior door?
Thanks

Hello again! You could consider our 58-056E. This has a .490" tall seal, which should be enough for your 1/2" gap. It also installs the same way.
Since your door is wood, you could also consider the 58-169. Rather than fitting into a precisely sized slot like the 58-056E and your original, this install using nails. That allows you to adjust it to the best possible seal before installation, allowing you a little bit more control.
