Description
The design of the “Cone” lock ensures intimate contact of the protective tube limiter to formwork surface and prevents the possible ingress of concrete into the pipe stopper. In a situation where builders are usinga handset without cones in order to conserve resources inevitably penetration of the concrete mass into the cavity of the tubeoccurs . In this case, the extraction of the anchoring screws when removing the formwork ties becomes difficult and even impossible.
