rollTREKVii is a robust continuous belay system perfect for high volume and harsh environments. Stainless Steel C.A.T.TViis (Continuously Attached Tour Travellers) and BilbiesVii provide a secure 'at-tree' bifucating belay/zipline journey. Dual polymer sheaves minimise flight noise and ensure forward flight when used on Ziplines. The suspension assembly includes a purpose designed spreader bar to maximise guest comfort and visibility. Used at Hollybank, Otway and the teamTRAILVii.
