This Saf-T-Grid allows you to safely install a fan or lighting fixture on a suspended ceiling. This complete kit features an ingenious design that allows all weight to be carried by the building structure, not by the gridwork, and a turnbuckle for easy height adjustment. For added ease, the electrical box can be positioned anywhere on the grid to fit your project needs. The grid support fans and fixtures up to 50 pounds and comes with everything you need for installation. It includes a Saf-T-Cap to protect bolts and wires during drywall installation and painting.
