Viro® VR4217 'Eagle' Fastening Unit

Easy to install and practical to use, this fastening unit for roller shutters is compact with rounded edges and pull-resistant. It is secured on top of the roller shutter jamb.

The stainless steel lock bolt (Ø 21 mm) is protected by a rotating ring, resistant to attack. It is closed by turning the key (to prevent motorised roller shutters from damage) and “grabs” the roller shutter section where a hole was made.

Unlike other fastening units, there are no components to position or remove every time you open or close it. Moreover, since it is not installed on the floor, it is more protected against atmospheric agents and dirt.
