Roxtec knock-out frame transit
The Roxtec knock-out frame (KOF) is a lightweight cast-in multi-cable transit that keeps your site dry during and after construction. The built-in knock-out plate maintains an environmental seal until it is knocked out prior to cable routing and installation of sealing components. The standard Roxtec RM sealing modules are adaptable to cables of different sizes and can be used to build in spare capacity in the transit. The KOF with plate can also provide spare capacity for future needs. By adding KOF adapters, the overall frame depth can easily be increased in steps of 50mm to fit walls of various thickness and at the same time eliminate the need for casting molds. The KOF has an integrated clip-together feature which provides mechanical connections to form space efficient clusters.
