The Fischer DuoSeal is a 2-component plug that seals the drill hole in wet areas without any additional sealing compound. The nylon plug with the enclosed screw has been independently tested and confirmed watertight in accordance with ETAG 022 and DIN 18534 up to the water exposure class W3-I. Suitable for commercial, private, and public wet areas exposed to splash water and temporary accumulated water. Ensures high load values due to the 2-component material and easy installation. The red component made of high-quality nylon activates optimum function depending on the building material for best hold. The stainless steel screw is ideally suited for wet areas and prevents rusting. Prevents structural damage caused by moisture. The rim of the shaft prevents the plug from being set too deep and additionally seals the drill hole. Grooves in the plug shaft compensate for unevenness in the hole. Please note national regulations on the use of plugs in wet areas.
