These 32mm fittings suit the Pairs Empathy Mk3 Breastplate sets (Pony, Cob & Full Size). They are included as part of the complete set

They are fitted by looping over the male part of the trace buckle (stitched onto the Empathy breastplate). The traces are buckled in and the tail of the trace threads through the trace fitting and into the keeper on the breastplate to hold it securely in place. The uptug buckles into the saddle top-strap, while the tail buckles to the false bellly band.
