When you use or replace straps on your tree stands DO NOT use polypropylene straps (cheapo cargo straps). According to a paper published by North Carolina State University, polypropylene can only manage six days before losing up to 70% of its strength as a result of UV rays. Polyester fares much better. The article reveals that following 12 months of UV exposure, over 67% of a component’s strength is restored. When ordering replacement straps always get ones that are UV protected.
VAPA your club is begging for a liability lawsuit. Wooden stands are just too dangerous. Even treated lumber exposed to the elements will rot especially around the screws/bolts.
