Applications

Installation notes
- Fix the base with anchors that suit the floor: chemical anchors in concrete, through-bolts in steel, or structural screws into solid timber.
- Check that the floor or stringer can carry the guard loads before you choose the anchors.
- Check the guard height for your project in our glass railing code requirements guide.
