Factor 55 ProLink E (Expert): a safer, smarter winch shackle mount that replaces the hook and accepts either end of a 3/4 in. screw pin or 1/2 in. soft shackle.

• Engineered and machined in the USA from lightweight billet 6061 aluminum to deliver durable strength without added weight, providing a reliable replacement for the conventional winch hook.
• Removable oversized 5/8" double shear pin securely captures the cable or rope eye inside the body for a stable, load-path connection.
• Accepts either end of a standard 3/4 in. screw pin shackle or up to a 1/2 in. soft shackle for versatile rigging options.
• Compatible with both hawse and roller fairleads to maintain proper alignment and minimize line wear.
• EPDM rubber guard protects the line and seats neatly against either fairlead type, reducing debris ingress.
• Compact footprint and weight—4.0 in L × 6.0 in W × 4.0 in H; 2.13 lb—designed for straightforward mounting on a range of winch setups.
