The cartridge grips are now active on our website. This first batch will come with a short and extra long drive bar. To be honest, the short drive bar will work on all machines. We will come out with a medium drive bar starting in March for those that want something a little longer than the short and shorter than the extra long bar. But the short drive bar should do it all.

Extra drive bars will be available in March as well for those that want it fully disposable. We are ramping up on production as we speak for those.

Thanks to everyone who has been interested in this product!
