Universal Right Keystone
Specifications of Universal Gray Right Keystone:
Used together with the left and center keystone blocks, the right keystone enables you to add a charming architectural effect to your door or window design without starting from scratch. Its innovative design and material allows you to install it in minutes, rather than the days or even weeks it would take to create a keystone look with real stone or brick.
Add keystone blocks above a window, doorway, arched entrance, even a garage door. Their polyurethane composition resists all forms of severe temperatures, weather and pests – ensuring your design will remain intact with no needed maintenance.
