The Raumer bolt hanger Alien 10mm is a very special hanger. It has 10 separate carabiner eyes. This is desirable wherever you want to attach two independent carabiners to a fixed point. And in such a way that they do not interfere with each other and one does not pinch off the other. This is the case, for example, with fixed ropes or fixed abseil routes.
The lug is also ideal for the increasingly common use of ballast resistors. Such as the Edelrid Ohm.
It 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.

Avoid galvanic corrosion
Only A4 steel quick links may be screwed into the Raumer bolt hanger Alien 10mm. Zinc plated screw links lead to galvanic corrosion of the base metal. Therefore, make sure you use the right quality of steel when fitting.

Not suitable for bolting near the sea!
The Raumer bolt hanger Alien 10mm is not suitable for bolting near the sea. The AISI 316L steel does not meet the required corrosion class. In order to withstand the extreme chemical conditions in the medium to long term, products made of duplex steel are required as a minimum.
Perfect for bolting near the sea:
- glue in bolt made of titanium
- glue in bolt made of HCR steel
- injection mortar for use near the sea
