Heavy Duty industrial strength bands I get custom made that are used to tie off the Sandflail opening. I ship each Sandflail with 2 bands as standard. These are heavy duty bands, they have to be strong but most importantly flexible enough to be able to wrap around the Sandflail 2 times so the compromise is that if you’re too rough with them (stretching too far) over time they can snap. So it’s better to open the band with your hand a bit and pull the material through instead of trying to muscle the band over the material. These are replacement bands or spares if needed.

Thanks for looking.
