Neat Finish, Strong Edge – Composite Prime HD 3D+ Bullnose Board
The Composite Prime HD 3D+ Bullnose Board is a finishing touch that ties your deck together neatly. Designed to work with the Composite Prime HD 3D+ decking range, this bullnose board creates a smooth, edge around steps or decking borders – tidying up the look while adding some extra grip.
