In these safety poles, energy absorption has been achieved by hollowing out the inside of the lower part of the pole, the most likely point of impact. At the same time, the hollow space leaves room for the fuse and cables, so there is no need for a separate power box. You may also choose a pole model that contains a hollow space only for electrical wiring. You may choose between an aerial or underground cable model. The wooden poles can be mounted to SJP wooden pole bases, and they have been finished with turnings to guarantee optimal compatibility.

Adding a concrete SJP base significantly increases the reliability of the safety pole. The concrete base prevents the pole from rotting and extends its service life. According to the most recent instructions provided by the Finnish Transport Agency, wooden poles should no longer be installed directly in the ground without a base.
