ŁSO connector is an innovative solution developed by company JONIEC. In the production process of splitting, tiles are created. Thanks to ŁSO connectors the useless GP tiles can be connected and used for building foundations and walls. The tiles have special insets to fix ŁSO connectors. First, these links were made of concrete, but now they are produced of plastic. This system is excellent when horizontal armament is required. The metal rods can be placed in different positions what strengthens the armament and facilitates construction of a fence.
