This is a Radius Arch and is made to measure with your choice of profile. It comes as 2 arch sweeps.
The arch sweeps are semi circles, thus the name Radius Arch.
If corbels are required, they should be purchased separately.
This radius arch can be made to any diameter up to 1500mm. For larger arches please see AR15002.
Step by Step
Measure the width of the passage, hall or other location.
At this time, you can also measure or workout the width of the NIB as this influences your choice of corbel.
You can find more detailed instructions here.
The profile of the arch can be selected on Arch Profiles.
Note the profile and use it when ordering (above).
