Hunt Master Speargun Parts - Stainless Steel Double Pulley for Spearfishing & Underwater Hunting Gear Replacement

The Hunt Master stainless steel double pulley has been designed specifically for easy and smooth loading and shooting of any invert-roller speargun.

Made from a combination of 2mm thick, marine-grade stainless steel with pulleys made from the incredibly strong Delrin®, a highly adaptable material that bridges the gap between plastics and metals and offers unique properties.

DuPont's Delrin® acetal homopolymer is specified for high-load mechanical applications and precision parts, where strength, stiffness, stability and reliability are important yet a plastic material is preferred to a metal. They are often used in gears, pulleys and other high-tensile parts where metal is not desirable.

Key Features:

• Designed with an anti-slip mechanism to resist the line coming off the rollers under normal use.
• Loading line / Dyneema is self-contained between the 3mm deep grooves of the hardened pulleys
• Pulley wheels developed from Delrin, with extremely high wear-resistance, strength and stiffness.
• Built with laser-cut, hardened 2mm-thick marine grade stainless steel.
