A multi-purpose penetration unit

The Sewatek D series firestops are ready-made service penetrations intended primarily for existing structures, which is why they are often referred to as renovation or second-stage penetrations. The service penetrations will be installed in to a drilled hole. The are different dimensions of the product in the series and the service penetration is easy to shorten according to the thickness of the construction. In addition to concrete and brick constructions the product series is also accepted for massive wooden constructions.

The product is also available via Würth under the brand name Würth SPS. For more information, contact your nearest Würth Center.
