Try upgrading your vendor list and find a, real, commercial door hardware supplier.

Have you measured your door depth and then done an internet search for that size?

Thanks all
I have measured the door. It is standard. I'm sure there is something a tad off as that is typically the way my luck runs. I will look for commercial door hardware suppliers though. Thanks for the tip.

Doesn't make sense, keep looking. Are you really sure it's standard? Most of these things are adjustable.

Most exterior doors are 1 3/4" thick. The mfg. of the knocker/peepsite combination is where I'd be looking.
