Sleeve with knock-out plate for sealing prior to cable and pipe routing.
The Roxtec knock-out sleeve (KOS) keeps your building dry during and after construction, and provides spare capacity for future needs. The sleeve is easily fixed and cast into structures of varying thickness and ensures a tight seal until its plate is knocked out for cable and pipe routing. The sleeves have an integrated feature which allows them to be connected into space efficient clusters. Once cables or pipes are routed, they are to be sealed with Roxtec UG™ underground solutions in the corresponding size.
