These have the maximum span of 880mm. with 17 radial bricks (see illustration below). The span can be reduced by removing bricks in 52mm. to 60mm. stages to suit your particular requirement in fitted width.
The soffite (underside) is 215mm. at maximum, though this can be reduced in size.
The radial (upright) bricks are 235mm. high. These can also be reduced if required.
In the near future we might market complete arches. Please enquire costs and availability of these.
