Drop & Lock comprises panels with returns that engage into vertical mullions using interlocking components. Once the mullions are laid out and in place, the panels are easily mounted. Installers lift the panels into position, insert L-shaped prongs into corresponding slots in the mullions, and drop them into place. The shape of the prongs and gravity immediately lock the panels into the mullions.
Great for any vertical wall application, we help your team choose the best material, surface treatments, panel sizes, and joint patterns for your project’s design and budget.
