Saddle Washers (Calottes)

Features and Advantages

• Precise Fit:

  Each saddle washer is exactly matched to the respective trapezoidal profile – for a perfect seat and maximum stability.

  Prevents the metal profiles from denting or bending at the fastening points, thus protecting the roof skin.

  These washers enable fastening on the crown (high rib), avoiding water ingress in the water-bearing area (valleys).

  Manufactured from robust, weather-resistant materials that offer long-term stability and corrosion protection.
