Cut AH-401 Lean Frame Extrusions less than each side. Slide the AH-401 Lean Frame Extrusion onto the edge of the panel, and fold using the AH 410 Lean Folding Handle as pictured.
Repeat step 2 on all sides of the panel. At each corner, slightly bend the fastening flange, and fasten the extrusions to each other with a #10 self screw as shown.
Clean surfaces and turn AH-406 stiffener under both AH-401 frame extrusions. Fasten stiffener to the perimeter extrusions with a #10 self-tapping screw in opposite corners as shown, then add structural caulk on both sides and tool it in.
