The BTM Bolt-On Tree Mount, part of an arbor-focused offering from Auroralight, is a simple and robust solution for use when a solid mount is required or preferred over our passive Tree Strap. The BTM is machined from solid brass for durability and features a nylon base with multiple wire exit ports. The BTM has a standard ½” (NPS) Thread that is compatible with most fixture brands. When installed onto solid timber, it is robust enough to support our largest luminaires. For easy and safe installation, pre-wire the luminaires on the ground, and use the supplied stainless-steel retention clip to hold connectors inside each brass fitting.
