The 10655 panel to panel coupling is made of heavy duty 0.100” thick solid stainless steel, is 12” long and comes with 8- 3/4” stainless steel self-drilling screws. It will greatly increase the strength of the joint anywhere two panels need to be bolted end to end. They can be installed on the top and bottom of the panel connection for the most strength or just on top if less support is needed. A use example would be bolting two 10’ side panels end to end to create a 20’ side panel.
