ABSTRACT:
A preform for use in constructing an archway wherein opposing sheet metal cheek are spaced apart by a curved throat to permit the cheeks to reside between the adjacent wall support and the overlying wallboard or drywall. The preform is affixed directly to the support members. Drywall is fastened to the preform by screws with the seams between adjacent drywall sections being covered in the conventional manner. The attachment of the preform directly to the wall supports essentially eliminates the likelihood of joint separation or fastener movement after installation.
