Lower off/Pull through chains

[GT]

Any thoughts (including competitively priced suppliers!!  ) on what people are using for pull through chain lower-offs?

I was looking at 8mm A2 (304) or A4 (316) stainless steel chain with 8mm SS maillons, but would be interested to hear others experience.

These will be for use in metal mines, rather than caves.

Cheers

The peak has some pull throughs that are made of stainless wire with swaged loops, fixed to a ring at the bottom and P bolts at the top.

Lots of commercial products available,

I've got 3 of these: https://www.alpkit.com/products/fixe-stainless-steel-glue-in-belay-station
I was going to put them in Bwlch y Plwm but did not in the end so let me know if they are of any use to you.
The Peak area pull through sets are good but made to order.

Rings last best (as long as they are decent quality), as wear point changes.

Cheers Pete, I'll mention it to Baggy who's looking after Bwlch y Plwm (which is where the lower-offs are heading).

Cheers all for the comments

I think 316 would be better than 304 where ever you place it, albeit a bit more expensive.  Bolt Product twisted shaft anchors will be a bit more difficult to remove in years to come than a single shaft anchor but I don't like welded eyes, see http://ukcaving.com/board/index.php?topic=20334.0.  But as you have welds in all components I am not sure if that dislike is relevant.
