Universal keystones, trim blocks are need-to-have architectural accents that mimic the look of their real stone counterparts, allowing you to add charming detail to your archways and window frames without undertaking hours of expensive masonry work.
The keystones are available in three pieces that can be used alone or together, available in neutral gray and tan to add a beautiful decorative accent to a doorway, arch or window indoors or out.
Surround a curved window or door with trim blocks, easily creating a nice turning point between the entrance way and surrounding wall without need for cutting or mitering to fit.
Products from the Universal line are made of heavy-duty yet lightweight polyurethane material, making them impervious to moisture, extreme climate, even pests. A complete installation can be finished easily by the average homeowner, with step by step instructions to help you all the way.
