The spreader is a handy tool for help in building a guitar. The picture of the mold show how they go in. The mold is not included.  Let me know what mold you need them for and we can make the spreader to fit the mold. There is a neoprene padding to protect the wood .  This  will fit through the sound hole when the body is assembled.  The turn buckle makes adjusting the spreader a snap .  The picture shows a dred  but this is for a 000  00 and 0  12  or 14 fret.
   Thanks again
