Adjustable Ratchet for your Moocall device. If your ratchet has become worn or damaged and is no longer getting grip on the strap you can replace it by unscrewing it.
This innovative new rubber has a brand new design, and it is designed to be worn looser on the tail. You don't need to use the ratchet system, simply pull the strap through by hand and that should do the trick. You should be able to slide the sensor up the tail, but you will notice it will not slide...
Longer strap for your Moocall device. Use this strap if you have bigger tailed animals and are struggling to close your Moocall with the regular strap. Important: Using a short strap on an animal with a larger tail may result in false alarms due to over tightening.
