Machined from solid stainless steel, the TA-3-FRC Rock Claw foot bites into hard surfaces to keep your tripod feet from slipping. Accidental Backout Prevention (ABP) O-rings keep feet securely in place. If you do not intend to use Rock Claws or Foot Spikes, we recommend fastening your original feet with non-permanent thread locker fluid for added security against accidental loss. Our stainless steel Rock Claws are sharp; use with care. Purchase one for $32, or three for $93 ($3 savings); discounted price automatically applied when you add three to the cart.
