Description:
There are two models, one with teeth and one without. I recommend the model with teeth. This will prevent slippage of the straps.Update 28SEP2018: I uploaded a strap keeper to hold the straps together.Although it looks very similar to the original model, this is a complete redesign. I made some changes that suited me better
