To achieve the correct corner intersection, the TS206 Perimeter Frame is positioned precisely on the panel edge to obtain the size joint desire. The TS203 Corner Clip controls the intersection of the two panels and automatically aligns the panels and creates the proper joint condition. The corner clip can be pre-attached in the field to one panel frame (as shown) or it can be attached to the substrate wall first to guide both panels into position. The size of the joint between panels is controlled by the placement of the frame on the panel edge. The joint size should be specified by the designer. Caulking of desired color can be added.
