Worthington Arches are available in sizes from 24"
up to 48" as one complete half round. Sizes 52" and
up will come as two 100 degree arcs. Worthington
Arches are made as true half rounds with 3"
extensions on the bottom. This allows Worthington
Arches to be adjusted to height on the jobsite and
fit all half round windows. This holds true
throughout our line except for 10-324, 10-324-3,
10-200 & 10-200-3 which do not have the extensions.
We also provide a pair of "shoes" with each arch,
which can be used to transition from the straight
section molding to the arch.
