This Bühler bolt with 2 rings is a high quality hook from Climbing Technology. Another popular name is “glue in bolt with 2 rings”.
It is made from AISI 316L stainless steel and has two welded rings. These have an inner diameter of 40 mm and a material thickness of 8 mm.
The glue in bolt itself has a shaft length of 75 mm. This makes it ideal for all compact rock types. And secondly, it has no load-bearing weld seam. This means that corrosion cannot occur at the welding point. This design is currently the safest and most stable on the market. The shaft ultimately has a 12 mm diameter and therefore requires a 14 mm drilling hole.
In short. If you are looking for a high-quality glue in bolt with 2 rings for abseiling points, you’ve come to the right place!

Ideal as an abseiling point
The Bühler bolt with 2 rings is ideal for equipping abseiling points. We recommend installing them in pairs or in series to create a redundant system.
The glue in bolt with ring are placed diagonally on top of each other at a distance of approx. 20 cm.

Bühler bolt with ring – rope is exposed!
The design of this hook means that the climbing ropes are exposed in the 2nd ring. This makes it much easier to pull off the rope than with hooks with only 1 ring.
Therefore, pay attention to the terrain when choosing a location. Avoid additional obstacles or rock formations that could cause unwanted friction. Such as the edges of ledges. The glue in bolt should be set as high as possible above such ledges with 2 rings.
Glass mortar cartridges vs. injection mortar
We recommend that you install this Bühler bolt with 2 rings with injection mortar to install. Especially if you are placing several pitons in a row. For example, on a longer abseil route or in a climbing area.
This is because setting with glass mortar cartridges requires a lot of experience and practice. In addition, it often depends on the weather conditions. Or to put it better. In very hot weather, the use of glass mortar cartridges is even trickier due to the extremely short curing time!
If you still want to use cartridges, the Fischer RM 10 is the right cartridge for you.
