The 4’ Extension is used to make our 4’ x 4’ tree grate larger or to add on to another extension. The 4’ extension can also be used to help maintain a healthy tree or to help remove excess water from surrounding surface areas.
The key to any successful landscape project is to budget for ongoing maintenance expenditures, such as grate expansion as your trees mature.
