Instort- en holle ruimte vloerdoos serie 3300

The 3300 series is a unique floor box which can be used in concrete floors and in computer / raised floors. The smallest version offers 1 module, and the largest is equipped with a maximum of 3 modules of 45×45 mm.

A special housing tube must be used if you assemble the floor box in a concrete floor.

The flat stainless steel lid must remain open when cables are connected so it is important that this floor box is used in spaces where people rarely walk.


These 3300 standard floor boxes are available in a 1-, 2- and 3-way version and in addition to the 230V, have space for different multimedia connections such as data, HDMI, VGA/audio, XLR, CAI and Audio. There are therefore many possibilities with this series. OCS has naturally already designed many of these which you can see in the article number overview below. The floor boxes are always delivered complete with sockets and if you wish with multimedia connectors.
