How are tree guards attached?
On Broxap systems, the tree frame is supplied with lugs to which the guard is bolted. If a tree guard is not required the frame is supplied without lugs.
A guard may be fitted at a later date but would be supplied with spiked legs which simply stick into the ground.
Buderus systems use a clip arrangement which secure the guard to the grille itself.
Can a tree grille be fitted after a tree has been planted?
Yes, by utilising detachable central supports on a medium duty frame.
