At Core Climbing, we make everything to the highest possible quality to ensure the maximum safety of our customers. To ensure as safe use as possible, here’s what you need to know.
Please read before commencing setting:
i. Holds should be fixed to a flat surface – uneven surfaces risk the hold spinning and/or breaking upon attachment.
ii. All holds (excluding screw-ons) can take either a countersunk or cap head M10 bolt as standard. For larger holds or holds with an elongated shape, we have added an M5 counter screw placement to prevent spinning on wooden walls. For GRP or concrete surfaces where secondary M5 screws are not possible, a risk assessment should be carried out to determine the likelihood and impact of holds spinning and the suitability of each hold for the substrate it is to be affixed to.
iii. For the Mini Volumes & Super sets (and any hold with an M10 bolt and more than one M5 screw option), we recommend using a bolt and minimum 2 screw placements, one at either side of the length of the hold – ie. Select the two furthest screw holes away from the bolt hole at opposite ends of the hold. When setting at height, it is good practice to use all available fixation points. Our Fibreglass Volumes should be attached using all available screw placements.
iv. For our Super sets, Mini Volumes and any holds where multiple screw holes (+3) and a bolt hole are present, these can also be fixed with just M5 woodscrews if desired, using all available M5 screw placements. The exception to this is our Geo Super Sloper set that have just two M5 screw placements and as such also require the use of an M10 bolt (and both screws).
v. When attaching holds with M5 screws, fully threaded M5 woodscrews are to be used, ensuring at least 10mm of screw thread is protruding from the back of 18mm birch plywood or greater. Ensure sufficient torque to prevent rotational movement. Avoid using existing holes in the plywood as fixing points. Impact drivers are not recommended for fixing woodscrews as they can damage thread in the wood and the head of the screw if not used with care. Woodscrews are generally not recommended for repeated use and should be inspected or discarded after each reset.
vi. 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
The surface condition and age of the T-nut and bolt may change the torque value applied due to the change in friction, the accuracy of the tightening method can also greatly affect torque values. The compressibility of the wall surface can prevent torque values from being achieved and risk damage to the hold and/or the T-nut. 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. 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.
To effectively clean the holds we advise use of 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 fresh Gripwash and other acid wash solutions to be effective at restoring holds that may have dulled over time due to ingrained chalk build-up.
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 in an appropriate environmentally friendly waste bin, away from opportunities to remove and reuse.
Core Climbing holds conform to: EN 12572-3, Artificial Climbing Structures EN 12572-3, Artificial Climbing Structures Part 3: Safety requirements and test methods for climbing holds.
