The TS-HD Tree Strap Heavy-Duty, part of an arbor focused offering from Auroralight, is a passive fixture mounting system making it ideal for protection of valuable specimen trees. The TS-HD is machined from solid brass for durability and features a nylon base with multiple wire exit ports. The TS-HD supports luminaires up to 5.5lb in weight; and is supplied with two UV stabilized EPDM rubber straps to firmly hold the fixture with no tools required, while the highly elastic material allows for uninhibited tree growth. Up to three straps can be connected in a series which can be cut to length to accommodate 2″ to 18″ caliper branches. 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.
