Lower tensioning system for spearguns with roller roller heads, especially for inverter system rollers.

The frame layout allows the rubbers to be loaded in an extremely backward position, virtually close to the trigger, thereby optimising the overall performance of the propulsion system.

In addition, with respect to the horizontal reel clamp system, this new solution brings two important advantages:

• facilitates the loading of the rubbers (since the anchors are more exposed and without special bulkheads)
• Allows the rubbers to be loaded underneath the reel with no obstruction from the reel, in the most backward, advantageous position.

On the chassis, you can mount almost any speargun reel on the market (additional screws are included).

Made entirely of laser cut stainless steel, it is very easy to install on your speargun thanks to its easily patternable structure.

The end of the elbow has a knurled profile designed to be inserted inside the handle (a hole with a 5 mm tip is used, the end is inserted and the epoxy hole filled).
