Sustainable Bolting and Bolt Removal

   Chain Extenders

Chain extenders have a multitude of uses:-

Allow clipping a bolt placed too high.

Allowing a bolt to be set over an overhang but clipped from below.

Extending lower-off points when the only good bolt placement is inconveniently situated.

Make installing top ropes easier and safer by setting the bolt at the cliff top but allowing the lower-off to be over the edge to eliminate chafe.

We use only high quality 8mm long link chain with a breaking strain of over 58kN for safety, reliability and long life.

We sell extenders seperately for fitting to existing bolts or fitted into any of our bolts.

Standard chain length is 200mm nominal but any length is available
