Circular tree guard set out
Circular Tree Guard & Grille
(sub-surface fix only)
1. Dig appropriate sized hole for tree (approx. two times the width of the tree root ball and the same depth as
the ball)
2. Position and correctly orientate tree grille frame centrally over hole so that the top of the frame is at ground
level. Ensure that frame is stable
3. Check level of frame & re-instate ground level up to frame edge (ideally setting frame in concrete for stablilty).
4. Position tree in centre of hole and back fill over root ball. Do not back fill too far over the top of the root ball
or this may cause the trunk bark to rot, damaging the tree. Lightly tread down backfill to secure tree.
5. Attach the two grille panels to the grille frame using 8 no. M8 x 20mm anti-vandal button head bolts. Tighten
to 14Nm.
6. Fix down both halves of the guard frame onto the grille ring plates using 10 no. M8 x 20mm anti-vandal
button head bolts. Tighten to 14Nm.
7. Attach the two joining plates to the top of the frame (using 4 off 25mm x S14 pan head screws) to secure the
two frame halves together.
8. The tree guard fixing eyes can be used to secure the tree trunk if necessary.
IMPORTANT NOTE:
Ensure that stainless steel is protected during site cutting of stone – contamination from disc cutters will
produce corrosion on stainless steel components.
