The MTR425402 Tree Strap Heavy-Duty, part of a robust offering from Auroralight, is a passive fixture mounting system making it ideal for use on valuable specimen trees. The MTR425402 is machined from solid brass for durability and features a nylon base with multiple wire exit ports. The MTR425402 supports luminaires up to 5.5lb in weight and is supplied with two UV-stabilized EPDM rubber straps to hold the fixture firmly; no tools are required. At the same time, the highly elastic material allows for uninhibited tree growth. 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.
