For external uses WE SUGGEST to use swivel fittings with POLISHED STEEL finish, as they are more resistant to the corrosive effect of weather conditions.
The swivel fittings presented in the following pages are divided into two main groups:
- with flat head;
- with countersunk head.
These two groups are further classified in:
- models with fastening from inside the glass;
- models with fastening from outside the glass.
