New: Roxtec knock-out frame transit – KOF

Use the rectangular Roxtec knock-out frame transit to form an efficient barrier in concrete structures. The cast-in frame has a knock-out plate that remains tight until it is time to install your cables, pipes and sealing components. It is designed for Roxtec sealing solutions. In this way, the builder can leave a dry and protected site – with built-in spare capacity both for last-minute changes and future expansion needs. 

Lightweight recyclable plastic   

The frame is made from recyclable ABS plastic and designed for cast-in-place or prefabricated concrete walls. It is a lightweight, corrosion free and non-magnetic alternative to cast-in steel frames enabling a reduction of the CO₂ impact of the construction.

Adaptable to wall thickness

The KOF depth of 100mm (4”) can be adjusted to fit the wall thickness and thereby eliminate the need for casting molds. You just add the right number of 50mm (2”) KOF adapters and attach the frame with nails, screws, glue or magnets to the form work.

Area efficient clusters

Thanks to the integrated connection function, you can form space efficient frame combinations in any direction to fit your needs. The frame can also work as transportation protection when producing prefabricated shelters and kiosks.

Ensuring fire protection 

The Roxtec knock-out frame with Roxtec blue sealing components then form a fire rated and watertight transit for multiple cables. You ensure safety and operational reliability while preparing your project for future upgrades and regulations.

You can also use the Roxtec knock-out frame with black Roxtec UG™ sealing components for complete watertightness underground. Discover that version here.
