here we have our thin wall loam to handle converter.
this allows the loam to slide into the handle, and fit nicely, and when the loam is not in there it makes it just look cooler.
these converters hold the loam in place by a screw, the screw goes though the hole on the bottom of the proton gun handle, that they would have used to loop the metal wire though on the hero throws, allowing it to stay accurate to the movie and yet look cleaner. these don't come with the holes in place but the option can be added.
the standard size hole on these are 3/8th to allow most wires to pass though, but custom size center holes can be added as a option.
