MUFFLER ANTI-NOISE SUPPORT The Mufflers are a cushioned support in thermoplastic polyurethane: they solve the problem of wavering manhole covers that generate the annoying metallic sound when vehicles pass. The Mufflers are adaptable and are fixed with special hightight adhesives supplied to any manhole cover in hinged support. Resistant to abrasion and compression, they counteract the formation of scale and withstand very high or very low temperatures (-40/60 °C). clicca qui DEMO VIDEO Mufflers can be adapted to the shape of the frame by using the cutter, and are firmly fixed to it by means of a special adhesive, following cleaning of the support surfaces with the brush and spatula. The adhesive reacts and hardens with moisture, turning into a flexible, durable and resistant elastomeric joint, so it is preferable to moisten one of the two areas to be bonded beforehand. Can also be used on vertical surfaces. It is accompanied by a safety data sheet in accordance with Regulation (EC) No 1907/2006. Muffler Small Muffler Medium Muffler Maxi For square or rectangular manhole covers, 8 manhole stops need to be fixed near the corners of the frame. For round manhole covers, 3 manhole stops fixed in a triangular position are required to achieve the best result. Via Mario Corrieri, 16 | 05100 - Terni - ITALIA
