KPB Klacker Power Box
Unlimited possibilities at the touch of a button

With the KPB Klacker Power Box, we have set the standard for switchable shuttering magnets in the precast concrete plant. The KPB is the original and offers absolute reliability and durability with its integrated Pro-Magnet, even in difficult conditions. The magnetic retaining core is tested regularly in our own magnet production to meet the specified retaining force. The KPB is ready to accommodate adapters and various shuttering skin carriers, which offer countless usage possibilities and thus maximum flexibility for the future.

Fields of application

The Verbus rib screw connection offers countless possibilities for attaching shuttering skin carriers of all types and for integrating systems such as, e.g. Doka, Peri, H-beam carriers or RATEC shuttering systems.


  • Integrated Pro-Magnet
  • RATEC original automatic magnet system for optimum hold even under heavy loads
  • Maximum retaining force with minimal weight
  • stable, bent housing construction
  • Completely closed design
  • Demonstrably longer service life of the integrated magnet components

The Magnet in the box

Pro-Magnet – the basis of all our ideas

Our standard magnets of the Pro-Magnet series are used in all RATEC magnet components and shuttering systems. Our in-house magnet production allows us to tailor the magnets to the exacting requirements of our customers and thus realise numerous special solutions. In addition to the tried and-tested standard variants with a retaining force of 990, 1980, 2970 or 4620 lbs, we can also implement other designs and magnet strengths as required, or adapt the installation components structurally without losing retaining force. High performance neodymium magnets are used for the Pro-Magnet series, which are installed in-house in a patented process, resulting in our standard installation magnets. Stainless steel bandages and various coating steps and processes make the magnetic core extremely corrosion resistant. Our extensive know-how in the field of magnet design and application enables us to perfectly meet every customer-specific requirement.

Application examples


KPB Klacker Power Box

The KPB is the basis for all applications in shuttering construction. The KPB consists of a heavily canted U-profi le with an integrated automatic magnet system with a retaining force of 990 - 4620 lbs and screw connections for accommodating adapters.

HT stop adapter

The positioning aid is now available as an adapter solution for the KPB 2000. The adapter remains in place after the demoulding process. If the same geometry is used for the next element, the old shuttering pattern is restored. This is made possible by a hinged stop bar, which is folded away from the shuttering by approx. 80 mm during stripping. The adapter solution gives you the flexibility to use your shuttering components efficiently. / *without KPB 2000 (Art. no. 03255)
