Double-Lock DL25
Double-Lock DL25 is a structural panel that is mechanically seamed during installation. The panel is an integral interlocking system by design that installs in one direction from a given starting point. A double male starter panel is available (for a minimal set-up fee) and may be installed in the middle of a roof area to achieve a symmetrical layout. DOUBLE-LOCK utilizes the traditional SMACNA standing seam “double-lock” plate.

insulation (utilizing a bearing plate under each panel clip) over 22 ga. corrugated steel deck, and various solid substrates including plywood sheathing or nail base insulation.
Uses & Applications
Product uses include low to high slope roofing, vertical fascia, equipment screens, mansards, and wall panels. This system may also be installed on tapered roof areas.
*Note: Metallic paint finishes are “directional” and are not recommended for “double male” panels.
If a Watertight Warranty is required panel must be double-locked.

Our Warranties are Second to None
DMI total system warranties protect all aspects of your metal envelope system, whether that be the watertightness of the roof or siding, the Galvalume ® steel, or the durable PVDF KYNAR® finish. When looking at warranties for your system, it is important to note that not all warranties are created equal. DMI warranties ensure the watertightness of all flashing conditions, trims, curbs, valleys, and penetrations. Building owners are protected with a total system warranty - “from the deck up” when using DMI insulation, fasteners, and underlayment. Our warranties are backed-up by a full-service Engineering Department, generating project specific shop drawings. Quality control is monitored by a minimum of two on-site inspections by our Field Technical Inspectors. DMI Total System Warranties give building owners and design professionals confidence that they are receiving the highest quality and most complete warranty available in the industry.
