Fager's Secure Clasp for curb chains.

With this smart clasp, you never have to remember where to place the chain again. Fit the length once, then turn the clasp around and click it on the bit directly. You can then choose to take it off the chain, or the bit.

The clasp also secures the chain to stay in place.
It is also an excellent choice when riding with a double bridle. The bridoon will never get caught in the hook.

They are made in high-quality stainless steel.

The clasp will be stiffer in the beginning but soften with use.
