The Castle tree grille, allows specifiers to continue their choice of paving over the tree pit area.
Relaunching one GreenBlue Urban’s success stories, the Castle2 Tree Grille now delivers even more user-friendly features. This heavy-duty recessed tray system allows virtually any style of surround paving to be placed within the trays and continue right over the tree pit whilst providing structural support for overrun as required.
Supplied complete with irrigation and aeration functionality like the original Castle Tree Grille, the Castle2 now simplifies installation through convenient lifting hand holds, fewer fixings and an adaptable irrigation inlet.
The two most important new features are a new lifting bracket enabling safe mechanical lifting when trays are filled with heavy paving material, and the removal of vertical lifting sockets in the corners, giving a much cleaner above-ground appearance.
Another new, long-awaited feature is a new joining mechanism that enables unbolting and removal of trays even after being fully paved. This allows long term health due to being able to remove the inner tray set when the tree girth grows to dimensions requiring extra space.
