Info & Technical

Material

Only the highest-grade materials make it into Core Climbing holds. A reinforced composite resin makes them both hardwearing and high strength.

Core Climbing holds conform and exceed:

  • EN 12572-3, Artificial Climbing Structures
  • Part 3: Safety requirements and test methods for climbing holds.

Larger holds have been reduced to make them lighter in weight and easier to handle.

Our Volumes feature a high strength and low weight fiberglass composite system.

Fixing

All holds (excluding screw-ons) can take either a countersunk or cap head bolt as standard. For larger holds or holds with an elongated shape, we have added a counter screw placement to prevent spinning on wooden walls. For GRP or concrete surfaces where secondary screws are not possible, a risk assessment should be carried out to determine the likelihood of holds spinning. For the Mini Volumes & Super sets, we recommend using a bolt and all available screw placements. Some sets also feature a special 'mouse hole' around the outer circumference of the hold, to allow effective side pinning with a screw. Our Fiberglass Volumes should be attached using all available screw placements.

When attaching screws to holds, fully threaded M5 woodscrews are to be used, ensuring at least 10mm of screw thread is protruding from the back of 18mm plywood or greater. Ensure sufficient torque to prevent rotational movement. Avoid using existing holes in the plywood as fixing points. Plywood should be minimum 18mm hardwood.

All our bolt-on & screw-on holds should be fixed to a flat surface - uneven surfaces risk the hold spinning and/or breaking upon attachment.

The following torque settings are recommended for fixing the holds to an even, untreated and flat 18mm plywood surface using M10 Bolts (hold sets listed below are for size reference):

Small Holds - Mini Bolt-ons, Crimps, Mini Jugs, Micro Jugs, Small Crimps, Slots: 30 - 35Nm

Medium Holds - Pockets, Medium Jugs, Roof Jugs, Domes, Mini Wedges: 35 - 40Nm

Large Holds - Large Jugs, Pinches, All Slopers, Wedges, Mini Volumes, Super Sets: 40 - 45Nm

Please be aware that different wall surfaces require different torque settings to prevent spinning - smooth and gloss painted walls will need greater levels of torque applied to holds compared to grip painted abrasive surfaces. The quality of plywood and the age and type of T-nut will also impact on the risk of spinning. Where a counter screw(s) is utilised as a secondary fixing point, the lower torque setting can be applied. A full risk assessment based on the specific wall surface should be carried out to determine the likelihood and implications of holds spinning and necessary action taken.

Cleaning

To effectively clean the holds we advise cleaning with a jet wash. Higher temperatures can potentially damage the fine surface of the holds which could also affect colour, we recommend temperatures to not exceed 60 degrees C.

We also recommend the use of Benky Gripwash, following the manufacturers cleaning guidelines of 6 minutes exposure to a 50% or higher solution, and briefly rinsing in clean water afterwards. A pre-rinse in water will also help by removing the surface chalk and prolonging the effectiveness of the Gripwash.

Our testing has shown Gripwash and other acid wash solutions to be effective at restoring holds that may have dulled over time due to ingrained chalk buildup.

General Maintenance

We advise visually inspecting and checking holds for cracks, chipping, sharp edges and burrs at regular intervals in accordance with your risk assessment. We advise checking holds in the first few weeks after placement and then every three months. Holds should be removed at least once a year and inspected at the attachment points. If any damage is suspected holds should be disposed of immediately.


Damaged holds must be disposed of in an appropriate environmentally friendly waste bin, away from opportunities to remove and reuse.
