Blue Ring Expander
Budget-friendly tool for expanding elastrator rings during docking and castrating of calves, lambs and goat kids. Reduces chance of fly strike.
Use the ring expander to stretch elastic “O” rings over the tail or scrotum. When released, the rubber ring clamps the arteries shut. The tail or scrotum drops off in 7–14 days.
Fly-strike is less likely with this method than other methods because it's bloodless.

- Blue plastic handles
- Metal workings
How to Use
- Attach the "O" Ring to the expander.
- Squeeze the expander and allow enough room for the ring to be slid over the tail or scrotum (including testicles)
- Release the expander.
- Take your fingernail and push the "O" Ring off on each side.
- Double check that both testicles are actually in the scrotum below the ring. This can be tricky with baby lambs and kids because the testicles are small.
- Always ensure that both testicles are actually in the scrotum below the ring. This can be tricky with baby lambs and kids because the testicles are small.
- Applying rings before a lamb or kid is 24 hours old, up on its feet, nursing and active. To do so interrupts nursing and predisposes lamb to rapid death from E. coli problems ("watery mouth"). Many wait at least 2 days to apply on twins, triplets and orphans.
- Rubber rings can cause tetanus. Be sure to vaccinate ewes or does with a booster dose prior to parturition.
- Though it causes more distress (particularly ram lambs that are both castrated and docked), this lasts less than an hour if the lambs are less than 7 days old (because the nervous system is less developed).
- Rings (all sources) occasionally break so it's wise to check results a week later.

Worked as it should. One pin fell out right away but after fixing that it works fine. Lightweight.

I wrote a review on this bander back in 2013 saying it seemed pretty well made for a plastic tool. It is 2021 and it finally broke. I got 8 years out of a highly abused $10 plastic bander, applying hundreds of bands a year. I am impressed. Ordering a replacement now.
