Weather seal to fill 1/2" gap

Need help. I am replacing a weatherstripping product that looks like your 58-008 for an exterior steel front door. My issue is the gap I'm trying to fill is 1/2" ... assuming some compression is needed, I think 58-008 will work per Dave's professional comment below from an earlier online discussion with another customer. (I've copied the comment below) I've measured my closed/latched door from the outside and need to snuggly fill a 1/2 inch gap. The product I removed has a 3/8" kerf. 5/8" wide. Please help! Dave's comment: "Looking at the 58-008, it appears that the magnetic seal will expand up to 7/16" to fill the gap. You say yours is 3/8" up to 5/8". If you have magnetic weather stripping like the 58-008 then this should fit. This type is used by many door manufacturers."
