The ISC Stryder Foot Ascender is specially designed for durability and functionality. For the user, the smooth upward movement and good grip on the rope are major advantages. The ISC Stryder uses a stainless steel cam with a conical cam surface for positive engagement on the rope with minimal sheath wear. The spring is selected so that the device can be moved easily on the rope without unhooking. The cam lever is foot-operated but can also be removed to achieve greater pivot range. With an abrasion-resistant fastening strap, the ISC Stryder foot clamp can be adjusted horizontally and vertically as required to ensure the best possible position. Suitable for rope diameters from 8-13 mm. Made of aluminium, circa 200 g.
