Sustainable Bolting and Bolt Removal | Maillons, Shackles,Rings, Chain and Karabiners For building up belays, abseil stations and lower-offs. All of these components are tested by us to verify their quality and strength. Our rings are rolled and welded in-house. As well as the normal maillons we supply special safety shackles for building chainsets, these are stronger, more economical and less prone to theft. If you are building lower-off with maillons then you should take measures to prevent theft. A high strength thread locking compound such as Loctite will deter most, even more secure is to fill the threaded barrel with epoxy putty before screwing it up. This is sold in a convenient kneadable form for pipe repairs and similar.

Stainless Steel Maillons
Stainless steel maillons (quick links) for joining chainsets, lower-offs etc.
Breaking strains given are our test results.
The maximum opening size is given to help you choose the correct model.
For lower-offs we recommend the rope should run through 10mm or better 12mm maillons for longer life and to reduce rope wear but a ring and shackle combination is much better.

Stainless steel forged safety shackles
An economical way of building up chainsets etc with absolute security and cheaper than the equivelant strength maillon and with a larger opening.
These shackles are forged from AISI 316 and fitted with a shouldered bolt and security pin, not the normal weaker threaded pin. The nut is tightened up against the shoulder and the pin fitted, allowing the pin to rotate in use. Breaking loads are from our own tests.
We offer two types, the "Bow" shape and the standard "D" which we can supply up to 22mm pin diameter.
The "Bow " form has larger eye dimensions and therefore fits larger plate hangers better.

Rings
To ensure consistant quality our stainless steel rings are bent and welded by ourselves.
All rings have a nominal internal diameter of 45mm.
These rings are ground smooth on the inside to ensure they do not hang up on the bolt or hanger, preventing rotation or cause wear on the rope.

Karabiners
Stainless steel wiregate karabiners with a closed eye and bent gate for building lower-offs and abseil points.
Wiregates are the most robust system and self cleaning for use outdoors, normal karabiners are hanging upside down when used for lower-offs are usually lying against the rock and the spring mechanism tends to fill with water-borne debris - we have seen too many defective screwgates after years on the cliff to recommend them and use instead 2 wiregates back-to-back for safety, for this we recommend you use the pear shaped maillons listed above or two safety shackles.
