Our long glue in bolt with ring has the dimensions 12 x 150mm. This makes it the ideal choice for several scenarios. Such as superficially brittle limestone, holey conglomerate or simply soft sandstone.
We offer the hook with double abseil ring on the one hand, and with just one on the other. abseil ring. This means that you always have the right product when setting up an abseil point.
Like all our Vertical Evolution products, this one is also double passivated. This means that an extra-thick chromium oxide layer protects against corrosion. So if you fit this glue in bolt properly with the appropriate injection mortar can expect a service life of well over 50 years in the Alpine region.

Why such a long hook?
Countless safety research studies show that the forces involved in falls in climbing sports can reach a maximum of 8 – 10 kN. If you compare these forces with breaking load, you can see the extreme over-securing of fixed points, such as our long glue in bolt with ring.
Conversely, however, this means that If something breaks, it is usually the rock. And to prevent this from happening, there is this piton with such a long tie-in depth of 150 mm. This prevents breakage, especially if the rock surface is poor. For example, in the case of superficially brittle scales in limestone or holes in conglomerate.
With soft sandstone, you should ensure a large embedment depth anyway.
Long glue in bolt with ring – set correctly
This hook should always be installed in pairs, one above the other and slightly offset horizontally. This guarantees that the climbing rope can pass through without a hitch. In addition, you are secured redundantly if one of the points should fail.
In addition to correct positioning, it is particularly important to tie in precisely without overhang at glue in bolt. This means ensuring sufficient drilling depth( mark theSDS drill bit!).
