Изготавливаются из полипропилена и предназначены для использования в системах с максимальной рабочей температурой 80 °С.

Основные функции:

• защита концов трубной теплоизоляции толщиной 6 мм от сползания и механических повреждений при монтаже/демонтаже;

• маскировка среза теплоизоляции, благодаря чему конструкция выглядит единым целым, что добавляет завершенности и презентабельности готовой инженерной системе;

• быстрая и удобная цветовая маркировка систем холодного и горячего водоснабжения.

Защитные втулки имеют гладкую и жесткую поверхность, идеально подходящую для наклеивания маркировочных этикеток.

A climbing wall is an artificially constructed wall with grips for hands and feet, usually used for indoor climbing, but sometimes located outdoors. Some are brick or wooden constructions, but on most modern walls, the material most often used is a thick multiplex board with holes drilled into it.

Recently, manufactured steel and aluminum have also been used. The wall may have places to attach belay ropes, but may also be used to practise lead climbing or bouldering. Each hole contains a specially formed t-nut to allow modular climbing holds to be screwed onto the wall. With manufactured steel or aluminum walls, an engineered industrial fastener is used to secure climbing holds. The face of the multiplex board climbing surface is covered with textured products including concrete and paint or polyurethane loaded with sand. In addition to the textured surface and hand holds, the wall may contain surface structures such as indentions (incuts) and protrusions (bulges), or take the form of an overhang, underhang or crack. Some grips are formed to mimic the conditions of outdoor rock, including some that are oversized and can have other grips bolted onto them.
