throat latch

This term is a specialized piece of equestrian equipment, specifically used in draft horse harnessing. It functions as a critical safety and stability component, ensuring the collar stays positioned correctly against the horse's shoulders during heavy pulling tasks.

Because it is a technical term within the niche of horse tack, it is rarely encountered in general conversation and is almost exclusively used by farmers, carriage drivers, or livestock historians. It is a compound noun where the components describe both the location (throat) and the function (latch/fastening).
