When installing your banister on a concrete surface you need to use these specifically designed heavy duty anchors for your PROVA post. The package includes 4 screws and include caps in anthracite for a perfect quality finish to the PROVA anthracite post.
1 pack includes 4 screws so suitable for one floor mounted post and 2 wall mounted posts and to be used when fixings the post to concrete surfaces such as brick work, paving and cement bases. The posts are predrilled so very simple to install.
ATTENTION: You need 4 heavy duty anchors per post for floor mounting and 2 for wall mounting.
