For the horse that's pushing through your curb chain, on the muscle, blowing by barrels, having trouble rating, or just a fire-breathing dragon. This is the Boca curb for you!
The stainless steel beads give your horse more to respect, while the FlexRoller™ design still flexes to the jaw for a clean, consistent feel.
Small: Suitable for bits with a shank length of 4.5 inches or less and a purchase under 1.2 inches.
Standard (Most Popular): Designed for bits with a shank length between 5.0 and 7.5 inches, paired with a purchase measuring 1.5 to 2.5 inches. Measures 12.5 inches on chain and 11.5 inches max on leather.
Large: Ideal for bits with a shank length of 8.0 inches or more and a purchase exceeding 2.5 inches.
If choosing a large curb modification, please do the following:
Measure your current curb chain at the length that it currently fits on your horse with the hack/bit.
Type the measurement (in inches) in the notes before checkout.
NOTE: if you have a hackamore or combo bit with a short purchase, choose our “standard” size!
