A precise hidden-fastening cladding system combining long-lasting Kebony Clear wood cladding with the Grad® Mini Rail.
Formerly called Grad for Kebony, the Click-In Cladding™ System allows boards to snap directly onto factory-positioned clips for a faster, cleaner, and more consistent installation.

Kebony Clear Cladding Board
One clear-grade cladding board designed to produce multiple architectural aesthetics without requiring numerous custom-milled profiles.
1 × 6 Clear Cladding Board (#2682)
Actual dimensions: 13/16" × 5 11/16" Available lengths: 10', 12', 14', and 16'
One Board, Multiple Aesthetics
Grooves on the back of the board work with either Mini Rail option, providing a choice between two popular visible gap sizes.
Flexible Orientation
The cladding board may be installed vertically or horizontally, depending on the desired architectural appearance.
Natural Weathering
When left unfinished, Kebony naturally develops an attractive silver-gray patina over time.
No Custom Milling Required
The cladding board is available in standard lengths and is ready for use with the compatible Grad® Mini Rail options.
Grad® Mini Rail
Factory-positioned clips allow installers to fasten the aluminum rails to the sheathing or vapor barrier and snap the Kebony boards into place.
Pre-Mounted Clips
Patented clips arrive factory-mounted on the aluminum rails to simplify layout and board attachment.
Uniform Spacing
Precisely positioned clips maintain consistent board alignment and gap spacing across the cladding installation.
Built-In Air Gap
The rail system creates a natural air space behind the boards, eliminating the need for separate furring strips.
True Hidden Fastening
Boards snap onto the clips without visible face fasteners or conventional hidden-fastening hardware.
No Pre-Drilling
The system does not require pre-drilling of the Kebony cladding boards or Grad® Mini Rails.
Recyclable Components
The rail system is manufactured from 100% recyclable aluminum and POM polyoxymethylene components.
Mini Rail Options

System Accessories
Grad® Spacing Template
Included in the Mini Rail box. The template is positioned between an installed rail and the next rail to maintain consistent alignment and spacing throughout the project.

Select the G2171 rail for a narrow nickel-gap appearance or the G2172 rail for a wider shiplap-style gap. Both options work with the same Kebony Clear Cladding Board.
Confirm wall construction, rail spacing, fastening requirements, ventilation, orientation, board quantities, accessories, weather barriers, flashing, and applicable building requirements before installation.
