Skyrail CG-F Series Glass Balustrade System (base channel, face mount)
Description

The Skyrail CG-F Series is the ultimate and premium Face Fixed glass balustrade and fencing system, distinguished by its ability to offer unimpeded views combined with exceptional strength and safety in modern architectural applications.

Available in glass only configuration, using sentry type laminated glass, or with an interlinking handrail using toughened safety glass.

Engineered for versatility, the Skyrail CG-F Series has a number of innovative features:

  • Its double fixing design enables it to be “stood off”, so that it can be used over cavities, flashings and membranes.
  • The base channel can incorporate a fin post at ends to support an interlinking handrail and therefore not need to fix to the building wall

The Skyrail CG-F has a continuous base channel profile and when powdercoated offers a sleek linear design. This adaptability ensures the system can be seamlessly integrated into a variety of applications, from balconies and staircases and pool fencing.

All Altech balustrades come with a project-specific PS1.

Key Features
  • Face fixed
  • Continuous base channel system with an integrated internal clamp for secure glass fixing.
  • Glass panels do not require pre-drilled holes for installation.
