I am buying an Anderson storm door for my home, but they do not offer the bronze hardware. I have noticed that Pella does and sells just the replacement hardware. Would they be compatible?
You need to see what width door the hardware is made for.
You also need to know if the door you're buying has the holes for the hardware already drilled.
Some doors have mortised hardware, some surface mounted hardware.
An unholed door with surface mounted hardware will be fine to switch.
Mortised hardware will not work in an unmortised door.
"They that can give up essential liberty to obtain a little temporary safety deserve neither liberty nor safety."
