Spec Sheet

Grad™ Mini Rail

Grad™ Mini Rail clips are factory-placed in position, so the installer simply fastens the rails onto the sheathing or vapor barrier and snaps the boards on. The rails create a natural air gap so there’s no need to install furring strips ahead of time.

Based on the desired aesthetic, Mini Rails come in two different gap sizes and can be installed vertically or horizontally.


  • Patented clips pre-mounted on aluminum rails
  • Uniform spacing for the perfect look
  • Built-in air gap behind the boards
  • A true hidden fastening system
  • 50% faster installation time
  • Made of 100% recyclable aluminum and POM (polyoxymethylene)
  • No pre-drilling of the boards or rails required

Grad™ Spacing Template
Included in your Mini Rail box will be a spacing template. This tool is placed between an existing rail and the next rail to keep alignment and gap spacing uniform across the project.

Grad™ Riser Support
For roof lines or short runs, you can use the riser support to maintain the correct gap between the stud and the board. The riser support has an opening so you can face fasten the board using the Pro Plug® system for Kebony.
