Notch Rook

The Notch Rook is a versatile rigging component for arborists. Perfect for rope bridges, prusik pulleys, positioning lanyards and redirects. Designed for optimal performance and safety by Brandon Nance of SHERRILLtree and manufactured by Rock Exotica in the USA.

Features

• Integrated swivel (PAW) that minimises twisting in the climbing system and maintains correct alignment[1][4].
• Rubber-lined attachment holes that minimise carabiner movement and prevent improper loading[1][4].
• Optimal chamfered edges that prevent rope chafing and wear[1][4].
• Three attachment points for great combination possibilities – fits in the palm despite its versatility[1][4].
• Works excellently as a prusik-minding pulley, on a lanyard/flipline, rope bridge or redirect[1][4].
• Optimal accessory for a rope bridge on harnesses with rope up to 13 mm in diameter[1][4].
• High-performance bearings instead of bushings for smooth operation[1][4].
• Perfect component in an M-system for an eye-to-eye split tail together with other blocks[1][4].
• Can be doubled in a two-hook system for a proper and secure saddle connection[1][4].
• Not mid-line attachable[1][4].
