Pretensioning Kit with Line Guide

Kit 2 Pre-Tensioning Hooks + Line Guide - Sigalsub

The Sigalsub Kit 2 Pre-Tensioning Hooks + Line Guide is the complete solution for converting and optimizing roller and inverted roller spearguns. Made from high-quality stainless steel, the components in this kit ensure corrosion resistance, reliability in the water, and long-lasting durability.

What’s included in the kit

• 2 flat pre-tensioning hooks in stainless steel, for anchoring pre-tensioned bands to the speargun barrel
• 1 line guide in stainless steel, a pre-drilled plate with a loop for proper line management and guidance on roller spearguns
• Stainless steel mounting screws included in the package

Function and technical advantages

The pre-tensioning hooks attach to the underside of the speargun barrel and allow pre-tensioned bands to be hooked in place, both on roller and inverted roller systems. By positioning multiple hooks in sequence along the barrel, you can:

• Adjust the level of band pre-tension
• Split and distribute the lower loading load
• Make upper band loading easier
• Quickly manage the speargun power according to fishing conditions

The line guide ensures an optimal, friction-free path for the line, preventing snags during the shot and maintaining the accuracy of the propulsion system.

Compatibility

The kit is compatible with wood, aluminum, and carbon railguns equipped with roller or inverter systems. The hooks fasten directly to the barrel using the supplied stainless steel screws, with no need for complex structural modifications.

Materials

• Hooks and line guide in stainless steel — maximum resistance to saltwater corrosion
• Mounting screws included in stainless steel
• Precision machining for a safe and stable installation

Installation notes

1. Position the hook at the desired point on the speargun barrel.
2. Drill the barrel at the selected mounting point.
3. Fasten the hook using the supplied stainless steel screw.
4. Repeat the procedure for the second hook in the optimal position.
5. Install the line guide in the correct position to guide the line without friction.
