TheFuji BACK STOP Lock Nut System is an innovative solution designed to secure your reel seat with confidence. Engineered for use with standard Fuji pipe-style reel seats, this dual-locking nut system prevents reels from loosening under pressure, vibration, or heavy use.

• Dual-Locking Design: Main nut + secondary jam nut for unmatched reel security
• Back Stop Click Mechanism: Audible/tactile confirmation of a locked position
• Compatible With: Standard Fuji pipe seats (FPS, DPS, PLS, etc.)
• Prevents Reel Seat Loosening under heavy load, repeated casting, or vibration
• Ideal for Saltwater, Heavy Freshwater, and Jigging Rods

Recommended For:
Rod builders and anglers who demand maximum reel stability and locking confidence. Ideal for jigging, surf, inshore, and big game setups using traditional Fuji pipe-style reel seats.
