Geometric and Seamless

MLM panels consist of geometric shaped, flat surfaces. Each surface is precision-cut using a CNC machine at VS headquarters in Salt Lake City. Panels are quickly assembled onsite, and, to create the ultra-clean and seamless look Vertical Solutions is known for, a final layer of finish sheeting is installed by our finish carpenters. This dual layer creates a rigid and truly seamless final product. Vertical Solutions bouldering walls typically receive a hand shaped top-rail. Route walls are protected with hardwood at rope wear points.

Similar to the ARC wall systems, we offer many options to customize your gym’s walls, including color finishes, hardwoods, and textures. Keep it ultra-clean with our Baltic Birch veneer, add custom colors with paint to match your gym brand, or use different stains for hardwood details. As with all Vertical Solutions projects, each design is unique, distinguishable, and perfectly tailored to suit your climbing gym’s personality.
