Climbing spurs When dismantling trees, climbing spurs can be very handy to use. They come in various versions. There are robust steel models, but also lightweight aluminium ones. Most spurs are adjustable to suit your height. There are also different gaffs that affect the correct climbing position. Various support pads provide the right support while climbing. Most spurs have replaceable parts such as separate spikes and straps, so you will enjoy them for years.
