Different hold shapes lead to significant differences in the depth of the bolt insert hole. The occurrence of such a hole is considered unsafe and undesirable according to the European climbing holds standard – EN 12572 – 3. To solve the problem, HRT has launched a new product – the bolt plug.


By keeping the bolt constantly in place, this plug allows route-setters to prepare the holds and bolts on the ground and then just fix them on the wall nice and easy.
