Rein Clips: Nickel Plate
The swivel stops the reins from twisting and the closed scissor action stops the clip accidentally hooking onto something like a wire fence if your horse leans over while wearing the bridle.
It is recommend that you use these trigger clips to attach your own reins to the bridle, for easy swapping to the lead ring/loop for leading, groundwork etc.
Replacement Clips: If your horse has stepped on a rein and broken the clip, it’s easily replaced.
Better that the clip breaks than the bridle or the horse!
