Nowadays, the climbing gyms are works of art and the holds that adorn the walls are for something!
Here is an overview of the making of these wonders that grow at the same rate as climbing in itself.


It all starts with blocks of foam which, little by little, will shrink in order to get as close as possible to the future shape of the catch. We start by removing a large amount of foam, then the cuts are made smaller and more precise. For this, a lot of tools are needed, the finish is done with sandpaper to remove each imperfection and get a smooth surface. All the details matter: it is necessary for example to anticipate the angle that will take the fingers of the climber when it will catch the catch etc …

Make the climbing holds’ mould

Then, a mould is made to suit perfectly the “catch” that has just been cut. For this, put the plugin its location and pouring silicone around to obtain the mould. Lego is a versatile and colourful way to take hold. The size of the slot is adjusted according to the size of the plug (logic). To avoid waste, the excess silicone is recovered.

Filling the moulds

After the moulds come the filling of these. Urethane liquid is quite toxic, it is mandatory to wear a gas mask and combinations. At this point, manufacturers have about 8 minutes to empty a bucket before the component begins to harden. Small, urethane-free spaces are usually located behind large sockets to use less urethane and lighten the urethane. Indeed, the component is expensive and heavy catches are difficult to implement (and very dangerous if they come to the stall).

Demoulding the climbing holds

Urethane is left in the mould for 30 minutes before being removed. The timing is crucial: turn out too early and the catch will lose its shape, turn out too late and the catch will adhere to the moulds. These two results make it unusable. After that, the catches are left out (making them harden) for at least 4 hours and most of the time overnight.

Each socket is sanded to remove any imperfections. The rear face is levelled to facilitate placement on climbing walls. There comes the phase where the plugs are drilled so that the openers can easily and securely screw the plugs to the walls. And finally, each plug is cleaned before being packed and sent to the climbing rooms.
