The stainless steel plates are fastened from the outside via through-holes in the housing wall or alternatively by welding to the inside of the wall. This results in effective protection against vandalism, and the outsides of the housing remain free of attachments that do not match the design or that should be avoided entirely in the interests of easy cleaning. They make threaded holes, nuts and washers unnecessary during instal- lation. This eliminates the labor-intensive pre-installation of such parts as well as the need to hold them in place during tightening or loosening. The plate thickness s corresponds to the minimum screw-in depth of thread d 1 , which should be fully achieved. The holes d 2 receive tensioning or positioning pins, if necessary, making it easy to position the plates and the multiple-joint hinges. see also... • Stainless Steel Plates GN 7247.6 (with Threaded Studs) → Page 1368 Information 1 Material 2 Length l 3 Finish How to order 1 2 3 GN7247.4-NI-75-MT • Stainless steel AISI 304 NI Matte finish, ground MT • Stainless Steel Characteristics → Page 2166 • RoHS Specification 1 3 • Other plate sizes • Other plate geometries On request GN 7247.4 Stainless Steel Plates with Tapped Holes, for Multiple-Joint Hinges GN 7241, GN 7243, GN 7247
