HK Type (Seismic Pedestal)

Characteristics

HK method (Pipe feet method)

It is applicable to products certified as seismic raised floors by the Japanese Ministry of Construction.
In addition, a large effective space for wiring can be secured.
Customers are able to select a size depending on the design specifications.
