Horse 4-Ring Butterfly Bit | Stainless Steel Hollow Bar Mouthpiece & Curb Chain | BI-0018

BI-0018 Premium 4-Ring Butterfly Bit with Hollow Bar Mouthpiece

The BI-0018 is a full stainless steel 4-ring Dutch Gag-style butterfly bit featuring a smooth hollow bar mouthpiece and a curb chain. With four oval rings on each cheekpiece, this bit offers the greatest range of rein positioning in the butterfly range — from a mild snaffle-like action right through to a strong collecting contact — making it one of the most versatile bits available for riders who need maximum adjustability.

Key Features

• 4-ring Dutch Gag cheekpiece — four rings per side give four distinct rein positions, allowing precise adjustment of poll pressure, bar pressure, and curb chain engagement
• Hollow bar mouthpiece — smooth, unjointed, and lightweight; the hollow construction reduces weight in the mouth while maintaining a consistent, even contact across the bars and tongue
• No nutcracker action — the straight bar design distributes pressure evenly without pinching, making it comfortable for horses with a sensitive mouth
• Full stainless steel construction — hygienic, rust-resistant, and built for long-term durability
• Curb chain included — adds chin groove action when lower rings are used, supporting collection and refinement
• 12 sizes available — 10.0 cm (3.9") to 15.5 cm (6.1") for a precise, comfortable fit

How to Use

Attach reins to the top ring for the mildest snaffle-like action with no poll pressure. Progress through the second, third, or fourth ring to incrementally increase poll pressure and curb chain engagement. This step-by-step adjustability makes the BI-0018 ideal for horses in training or those that require fine-tuning between disciplines.

Ideal For

Riders who need maximum versatility from a single bit — whether schooling a young horse at the top ring or riding a more advanced horse at the lower rings for collection. Suitable for show jumping, eventing, hacking, and general schooling.

Size Guide: Measure your horse's mouth width from corner to corner and add 0.5 cm for the ideal fit.
