This extension piece can be used together with the insert for retaining wall L-blocks. This allows the standard size of 120cm to be extended to 150cm before placing it in the basic mould 150x60x60. Concrete retaining wall blocks with a height of 150 cm are ideal to transition from one terrain level to another, while maximising the usable land area.
