Use the XL Castrating Bander and reap the benefits of delayed castration with an easy-to-use tool. Designed for bulls from 250 to 750 lbs, this castrator tool works just like the plier type banders. Simply open the band, put into place, and release the handle of the applicator. No threading, tightening, or crimping of any kind. The castrator bander can also be used for removing horns and docking tails. Once the band is in place, the scrotum should fall off in 20 to 40 days. Use with bander bands.
