The Crocolock Band Hook from ermes sub holds tension on both bands' wishbone of a double roller gun set up. It goes positioned underneath the barrel of the speargun towards the handle, creating a loop point that holds tension on the bands while the speargun is loaded.
Thanks to its crocodile mouth shape, it prevents the rubber bands from jumping out after firing, while at the same time keeping them perfectly aligned under the shaft.
This new double crocolock band hook also allows you to mount a reel directly to the hook
Includes mounting hardware.
