Installation:
1. Prepare an excavation between fence post 3.3m wide by 2.2m long. The floor of the

accommodates a bedding layer 50mm thick and grid set down of 50mm. The latter
minimises silting up of grid and slows traffic down.

directions.
3. The cattle grid is lowered onto the prepared base. Ensure that no part of the unit it sitting
on any high points.

side to form a ramp. If depressions occur on these ramps with use add additional
material. Rearrange fencing to suit grid width if required
