A fishing leader holder designed by an angler for anglers

LEADER-LOCK | Fishing Leader & Hook Organizer

Designed by an Angler for Anglers

LEADER-LOCK was developed to solve a common problem: safely storing pre-tied fishing leaders without tangles, loose hooks, or wasted time rigging on the water.

It's especially useful for fishermen who prepare multiple rigs in advance and want an easy way to store, transport, and identify them.

Organize, protect, and store your pre-tied fishing leaders with LEADER-LOCK!

Keep your pre-made fishing leaders organized and accessible. LEADER-LOCK is a compact, reusable, fishing leader storage system designed to keep your pre-rigged fishing leaders neatly organized, protected, and ready for your next fishing trip.

Whether you're fishing inshore, offshore, or around the reef, LEADER-LOCK makes it easy to prepare your rigs ahead of time and keep them organized until you're ready to fish.

Key Features

• Protected Hook Storage: A recessed central compartment keeps your fishing hook safely contained beneath a removable press-fit cover, reducing accidental snags.
• Organized Leader Storage: Wrap up to approximately 30 feet of monofilament or fluorocarbon leader around the circular spool.
• 12 Line-Retention Slots: Open slots around the perimeter let you guide fishing line into the holder and secure the loose end.
• V-Groove Line Locking System: Two internal V-groove towers securely hold the leader with removable press-fit cylindrical caps, helping prevent the line from springing loose.
• Compatible with Multiple Hook Styles: Designed to accommodate circle hooks, J-hooks, and octopus-style hooks.
• Snap-Fit Modular Assembly: The reinforced front flange attaches to the main spool using integrated alignment pegs. No screws, glue, or additional hardware required when the press fits are properly adjusted.
• Removable Protective Cover: A ventilated press-fit cover helps protect the hook and includes an extended finger tab for easy removal.
• Reusable and Water-Resistant: Designed for printing in PETG, making it well suited for use around freshwater and saltwater fishing equipment.
• No Supports Required: The modular components are designed to print flat, minimizing material waste and post-processing.

Four Available Sizes

Each size features a central hook-storage compartment, circular leader-winding spool, press-fit protective cover, and two removable V-groove locking caps.

Hook Compatibility: The Medium LEADER-LOCK has been physically tested with circle hooks up to size 6/0. Smaller and larger holders are intended to accommodate proportionally sized hooks. Actual compatibility depends on hook manufacturer, shape, shank length, and wire gauge.

How LEADER-LOCK Works

1. Place your pre-tied fishing hook inside the central storage compartment, positioning the shank between the parallel retaining rails.
2. Guide the leader through one of the perimeter openings and wind the line around the spool.
3. Return the remaining leader through another opening into the central compartment.
4. Press the leader into a V-groove tower and secure it using the removable cylindrical locking cap.
5. Press the protective cover into place to keep the hook and leader securely stored.

Your fishing leader is now organized and ready to use!
