Raumer bolt hanger Anellox turned 10mm – AISI 316L

The Raumer bolt hanger Anellox turned is a so-called round hanger. This means that it consists of 8 mm round steel. As a result, this bolt hanger can be built in a completely different way. In the case of the Anellox twisted, this is a ring-like shape with an extremely large amount of space in the carabiner eye. There are also no sharp edges.

The difference between this and the standard Anellox flap is the twisted shape. This allows direct access to the drilling hole opening from above. This means it can also be used with concrete screws!

This brings us to the areas of application for this lashing. On the one hand, it is used wherever a lot of slinging gear is attached. For example, 3-4 carabiners or screw links. This is the case when installing lighting or several ropes in different directions. On the other hand, this lug is also perfect wherever a sling is moved back and forth a lot under load. This is the case, for example, with slacklines, pulley systems, lifting work, etc.

Thirdly, these types of lugs are very good for building rope railings. Unlike the sharp “normal” bolt holes, they are much gentler on the quick links.

Raumer bolt hanger Anellox turned – best steel quality

This turned lug is made of AISI 316L steel (A4 steel). It can therefore be used anywhere in the Alps. It is best mounted with 10mm A4 steel expansion bolt to prevent galvanic corrosion. Like all Raumer products, this bracket is simply passivated. This means that the protective outer layer has been further strengthened by an acid bath.

In short: this flap is a good choice!

Areas of application

The Raumer bolt hanger Anellox twisted is used for:

• Fixed points that have to accommodate many carabiner quick links
• Fixed points from which work is carried out in many different directions
• all “rocking” loads
• Rope railing
• Assembly work – hanging many ropes
• Wire ropes that are stretched from vertical to vertical wall (e.g. rope bridges)

Avoid galvanic corrosion

Only A4 steel quick links may be screwed into the Raumer bolt hanger Anellox twisted. Zinc plated screw links lead to galvanic corrosion of the base metal. Therefore, make sure you use the correct steel quality when fitting the links.
