Four String Binder
This Binder is Not for Sale
This was my idea of what I thought a four string should be. If you look at the two arms and spring, the spring sets the tension for both of the spools. They are exactly the same tension, no further adjusting necessary. The thread tubes extend six inches from the wheels, also the plastic tray extends through the wheels so the glue can’t get on anything. The binder works perfect—I’m just not a fan of four string binders, I prefer the Garrison style binder.
