The Lyman Trius Trap Main Spring (SKU: LY-TRISPR) is a heavy-duty, high-tension replacement component designed specifically to restore the throwing power of your manual clay target thrower. Over extended periods of use, original launcher springs naturally experience metal fatigue, leading to reduced throwing distances and inconsistent target releases. This genuine OEM (Original Equipment Manufacturer) replacement spring reinstates the mechanical force required to propel clay targets up to regulation distances of 50 yards (approximately 45 metres), depending on the specific trap model and tension settings. Engineered for seamless integration, it connects directly to the standard tension adjustment eyebolt and knob assembly on compatible Trius frames.

As a purely mechanical component, this main spring is ideal for the Australian shooting sports market. Because Lyman Trius manual traps operate via mechanical foot pedals or pull-cord systems, this part requires no electrical power, rendering it entirely exempt from Australian AS/NZS 3112 plug standards or SAA/RCM electrical safety certifications. Shooters across Australia can easily service their equipment locally, ensuring their clay launchers remain in peak operating condition for weekend practice or club events.

Key Features:

• Direct OEM Compatibility: Specifically designed to fit the Trius 92S Trap (SKU: LY-TRITRAP), the Trius Birdshooter 2 Trap (SKU: LY-TRIBIRD), and the Trius One Step Trap (SKU: LY-TRI1S).
• High-Tensile Steel Construction: Manufactured from premium, heavy-duty spring steel engineered to endure thousands of high-velocity tension and release cycles without premature deformation.
• Adjustable Tension Support: Works in unison with the original Trius large adjustment knobs, allowing shooters to easily modify spring tension for throwing singles, doubles, or piggyback doubles.
• Restores Factory Velocity: Replaces worn, stretched, or fatigued springs to bring the launcher back to its original factory-specified velocity and throwing distance.
• Weather-Resistant Durability: Built to withstand harsh outdoor range environments and temperature fluctuations common in Australian shooting locations.
• Enhanced Range Safety: Replacing a structurally compromised spring prevents sudden mechanical failures under load, ensuring a safer shooting environment for operators and bystanders.

Who It Is For:

The Lyman Trius Trap Main Spring is designed for Australian clay target shooters, property owners, and gun club maintenance officers who rely on manual Trius launchers for shotgun practice. If your current thrower is failing to reach regulation distances, releasing clays sluggishly, or showing visible signs of spring wear and rust, this replacement part is essential. It is perfect for those who prefer the reliability of mechanical, non-electrical field equipment and want a straightforward, tool-free tension adjustment setup to keep their shooting sessions running smoothly and safely.
