TREE GRATES INSTALLATION
All IRONSMITH TREE GRATE frames are :
Standard bolt in detail for saw-cut concrete or existing curb. Works with slabs 4" thick or greater. Often used in conjunction with other details on the same frame when working against an existing curb.
This rarely used detail permits installing a tree grate in an existing hole where the hole opening is the size of the desired grate.
Use this detail where DETAIL #2 does not provide adequate depth for anchor location. If using unit pavers on a sand setting bed DETAIL#6 or DETAIL #7 should be selected.
This detail can be used with pavers as shown although it is a more difficult form up in the field than details #6 or #7. This detail is best used for situations where the frame must butt against an existing structure.
This is our most popular solution for setting a tree grate into a field of unit pavers particularly when using a sand bed. Standard height is 3 1/4" for use with 60mm paver on a typical sand bed; however, other heights may be specified
