Mounting frame and coupling arrangement
A mounting frame, for example a UPVC door or window panel, has its hollow frame members secured together at the corners by a coupling member 205. The coupling member has legs, which carry resilient fingers which are pushed into the cavities of the respective frame members and the fingers sprag against the inside walls, so that the legs are firmly retained within the frame members. Use of the coupling member means that the mounting frame can be constructed on-site with ease and accuracy. <IMAGE>
