The bigger, stronger, “better” bander. Bands are two times the strength of standard bands and they open bigger. Banding causes less stress, resulting in bigger gains. Recommended for calves up to 400 lbs. or 3-4 months of age. The bands are flat so they will not roll off of the applicator. The scrotum should fall off in approximately 20-40 days. Vaccinate with tetanus toxoid according to label directions. Bander comes with 10 bands.
