Area of Application

The ISOSTOP systems are generally characterized by a slim design. This makes transport and installation in high alpine terrain much easier. They are an effective and efficient system used to protect life, infrastructure and other elements at risk. ISOSTOP 1:1 scale tested carrying both European and Swiss certifications.

Rope Guidances

Integrated Ladder

Post are constructed from a conventional profile-section. Each post has an integrated ladder composed of rungs spaced at 50 cm intervals in the webbing of the I-beam. The ladder assists in the installation of the fence as well as routine inspection and maintenance.

Base Plate

The universal base plates of the ISOSTOP systems can be used for compression-tension anchoring, as well as for placement on foundations or walls. The unique mounting bolt enables free-standing installation of the posts, which saves significant time, especially when assembling a helicopter.

Simplex Brake Element

Friction-based brake elements, such as the SIMPLEX brake, have a long history of proven use and impresses with its simplicity during transport, installation and maintenance.

Diagonal Wire Rope Net

This Diagonal Wire Rope Net is particularly insensitive to surface loads due to its stable structure and diagonal load distribution. The individually pressed cable connections ensure that the load is absorbed across the surface even if the net is damaged and offer great protection.
