A central hub includes a plate and a sleeve attached to the plate and adapted to receive a sprinkler head. The sleeve may be a telescoping sleeve. By providing a central hub with the plate and sleeve, the central hub provides increased stability and versatility to the sprinkler head. The plate provides additional stability and support to the sleeve, and thus the sprinkler head, rendering the combination better able to operate effectively when high fluid pressures are utilized. The central hub is generally attached to a support structure by some mechanism, such as a leg. The addition of the plate adds versatility by increasing the number and variety of legs that can be used to attach the central hub to the support structure.
