SMC"s new Pro-Tech Links were created so you could build your own solution to challenging rope protection scenarios. Pro-Tech can handle up to three moving or fixed ropes with captive pins that keep the ropes from-jumping the tracks." The polyacetal copolymer was rigorously tested for durability and a low coefficient of friction to ensure that your ropes will be resolutely protected from damage while still sliding cleanly over obstacles. The-tractor tread" design articulates to match virtually any terrain feature and the modular system is infinitely reconfigurable giving you unsurpassed flexibility and peace of mind when rigging. Pro-Tech Links are available in 1.8" lengths so you can create your own custom rope protection system.
