4 1/2 in Myler English Dee without Hooks Mullen with Low Ported Barrel

Engineered for dressage-minded riders, the 4 1/2 in Myler English Dee without Hooks with a Low Ported Barrel offers a tongue-friendly, independent rein response designed to improve acceptance and precision without palatal pressure.

• Size: 4 1/2 inches cheek length, sized for average horse heads to provide balanced leverage.
• Rings/Design: Dee bit ring configuration without hooks for a clean, secure feel and reduced risk of mouth injury.
• Mouthpiece: Mullen mouthpiece with a gentle, curved profile that prevents lip and bar pinching while delivering consistent pressure.
• Port Type: Low-ported barrel with a 3/4" high port, allowing the tongue to pass underneath and swallow comfortably without causing palate pressure.
• Material & Inlay: Stainless steel mouthpiece with a copper inlay for added tongue-stimulating contact and moisture retention in the mouth.
• Independence of Rein Action: Independent side movement ensures each rein can influence the corresponding side, aiding precision in lateral work and transitions.
• Dressage Compliance: 2012 USEF and 2016 FEI dressage-legal design—consult the rule book for specific competition guidelines.

This MB 06 model is a Myler alternative to the traditional Mullen bit, offering extra tongue clearance without sacrificing control. The low port reduces the risk of palatal pressure while maintaining effective communication through the lips and bars, making it a practical choice for horses that need a bit of tongue space during training and competition. Its curved mouthpiece and copper inlay promote comfort and acceptance, helping riders achieve steadier reactions during transitions, lateral work, and collected gaits.
