Curved Double-Lock
CR-DL15


Curved Double-Lock CR-DL15 is a structural panel which is mechanically seamed during installation. The panel is an integral interlocking system by design which 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.

Two different clips are available

Low Floating and Fixed.
