Cast Stone Keystones

Cosmetic Keystones Used in Conjunction with Decorative Heads

Our L shaped Cast Stone Cosmetic Keystones are manufactured with a fine surface, similar to natural stone to replicate the real thing. These used are used as a design feature above windows and doors. 

They are designed to be used in conjunction with our cast stone decorative heads, adding a creative spark to the exterior of any building.

We currently have two designs available, both of which sit above the window head:

  • Keystone cosmetic K1 unit is installed over a DH1 decorative head
  • Keystone cosmetic K2 unit is installed over a DH2 decorative head

We’re also able to manufacture bespoke keystone designs to meet your individual requirements.
