Versatile – The key with 5 mm internal square fits the valves of most standard radiators - older ribbed heaters are usually not compatible.
Small but fine – can also be used in smaller niches and corners – make sure to add enough space for your hand in addition to the tool length (4 cm).
Higher heating performance – Regular venting increases the efficiency of your heaters, reduces heat loss and thus saves expensive energy costs.
Clean work – The water coming out automatically collects in the collection container - splashes and stains on the floor are thus effectively avoided.
Well thought-out – The collection container is made of heat-resistant material. The top is equipped with a ventilation opening from which air can escape.
