The Fence POST-IN system is engineered for SRWs, utilizing the large hollow cores of the wall blocks to install either steel or wood fence posts.

The cantilevered POST-IN unit combined with a concrete slab and the soil behind the wall will resist the overturning pressure of lateral loads.

Placing the privacy fence directly on top of the concrete wall blocks allows for maximum land usage. It also allows substantially less maintenance behind the wall.
