Notch Rook

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

Features

• Integrated swivel (PAW) that minimizes twisting in the climbing system and maintains proper alignment[1][4].
• Rubber-lined attachment holes that minimize carabiner movement and prevent improper loading[1][4].
• Optimally chamfered edges that prevent rope chafing and wear[1][4].
• Three attachment points for extensive combination possibilities – fits in the palm of your hand despite its versatility[1][4].
• Works great as a Prusik minding pulley, on a lanyard/flipline, rope bridge, or redirection[1][4].
• Optimal accessory for rope bridges on harnesses with ropes 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 eye-to-eye split tails along with other blocks[1][4].
• Can be doubled in a two-hook system for proper and secure saddle connection[1][4].
• Not mid-line attachable[1][4].
