What’s special about Stal’s range of climbing anchors?
In the highly unlikely event that one anchor should fail, the second anchor will take over without any shock loading of the system.
Our independent modular system is comprised of easy to replace components. This increases the lifespan of our products and keeps costs down. Easily check and replace elements of the system that can be expected to wear with use.
Our anchor systems are compatible with all climbing walls and a range of other uses and can easily be fitted to any structure.
The ‘Puck’ & corrosion and wear reduction
Stal uses a polyurethane blend plastic outer cover for all our anchors. The puck reduces wear and corrosion and in certain circumstances acts as a shock absorber. It reduces corrosion by allowing airflow around the anchor components. This limits the capillary effect that is one cause of corrosion.
Stal uses a central maillon linking the two chains together to reduce movement in the whole system. This reduces the metalwork wear that is traditionally encountered from anchors that move when used.
The chain links that make up the Stal anchor systems are induction welded. This means the links are very strong and have not been made brittle from the welding or bending process. Each section of chain is polished to assist with corrosion resistance, ‘laser etch’ provides unique identification for each component. The chain is also plated for additional resistance to corrosion.
As well as being induction welded the chain links are certified to EN standards for size and strength. Each batch of chain is proof tested by the manufacturer and every section of chain is proof tested to 20kn in the UK before sale.
All anchors have passed independent testing for EN standards 12572-1 (artificial climbing structures standard), EN 959 (mountaineering standard), EN 795 (rope access standard) and UIAA 123 (mountaineering standard higher than the EN 959).
