How do I put climbing holds directly on concrete?

The climbing holds are fitted with M10 bolts. These are screwed into concrete anchors on the wall on which the climbing holds are to be mounted.
The length of the M10 bolts may vary. See our different sizes here.
Our climbing holds products are supplemented with recommendations for bolt lengths for wood, brick and concrete walls, respectively.

Course of action:

1. Make sure the surface is level (climbing holds may crack if they are fastned on an uneven surface)
2. Drill holes with a 12 mm brick drill bit
3. Push the concrete anchors into the holes with your finger so the edge is 2-5mm inside
4. Use a mandrel or other blunt object to knock the pile inside the anchor to the bottom (thus expanding the anchor and jamming it)
5. Tighten the climbing grips with an Allen key 8 mm

Tools and equipment:

• Concrete Anchors
• M10 bolts (stainless bolts if climbing will to be installed outside)
• Drill with 12 mm brick drill bit
• Hammer and mandrel to hit the concrete anchors
• Allen key size 8 to fasten the climbing grips
