QwikLok™ Panels are ideal for underhung applications; no more fighting with trying to install two panels at one time. Unlike conventional roofing cover, QwikLok can be assembled from the underside of the structure one panel at a time, producing a flush appearance with no exposed fasteners. The easy-to-trim flush surface makes transitions to conventional material simple without major concern for creating special conditions. QwikLok can be installed over a variety of substructures such as light-gauge framing, purlins, structural steel and joists.
