Technical Info

Tried and tested

Our holds are poured from Polyester Resin which gives them great resistance to wear and a solid, rock-like feel.

After mixing our resin and prior to pouring, we vacuum our mix to minimise the introduction of air into our casts – this increases the strength of our holds and prevents bubbles from affecting the surface texture.

We design and test our holds in-house to ensure they conform to EN12572-3 (Artificial Climbing Structures, Part 3 Safety Requirement and Test Methods for Climbing Holds).

Fixing to the wall

The vast majority of our holds are ‘dual-fixing’ and can be used as screw-on or bolt-on. This great versatility allows setters to place the holds exactly where they’re needed in order to create their envisioned masterpiece.

The holds take both countersunk and cap-head M10 bolts. On thinner holds, we advise the use of countersunk bolts over cap-head, as they help to evenly distribute any stress which may be applied to the hold whilst setting.

If using a bolt, we recommend that one of the screw holes be used to pin the hold to stop it rotating. A 5mm screw, with a full-length thread, should be used. We recommend that the bolt protrudes at least 25mm from the back of the hold when seated in the countersink or on the flathead.

The surface to which you fix the hold should be flat. If it isn’t the hold may rotate or break.

Bolts in small and medium sized holds should be tightened to 25Nm.
Bolts in larger holds should be tightened to 35Nm.

For smaller ‘screw ons’ we recommend that you don’t use an impact driver as this runs the risk of breaking the hold.

Cleaning holds

With use, your holds will get covered in chalk and shoe rubber that will reduce the available friction. A thorough clean should have them almost good-as-new. People generally use 3 methods to clean holds – they all work and shouldn’t degrade the strength or colour of the hold.

Dishwasher. Perhaps the most thorough method for cleaning your holds. Be sure to use a low-temperature wash to prevent degrading the colour. Load them up and press the button, simples!

Pressure wash. Load the dirty holds in a basket and fire the jet washer at them. Don’t be surprised if you get wet and the holds bang around off each other. If using a cold wash, you’ll need a minimum pressure of around 110bar to shift any accumulated rubber.

Benky or other similar cleaning product. These light, organic acids lift chalk and shoe rubber off the hold. The holds then need a thorough rinse to prevent any residue affecting the available friction. There are safety requirements and a need for personal protective equipment if you use this method.

Update on our move…

Stonesmith Holds are now out of our original premises and finalising the details of the new location. As a result of this we have temporarily stopped creating holds to order and have had to halt delivery on holds. If you would like to discuss a future order then please email hello@stonesmithholds.com. Apologies for any inconvenience caused and we hope to be back to normal as soon as we possibly can.
