ABSTRACT:
A weather cap for an exhaust pipe includes a mounting collar adapted to surround the exhaust pipe and including supporting arms extending therefrom. A resilient bumper is supported on a clamping bolt extending through the supporting arms. The resilient bumper includes a portion extending above the collar so as to be engageable by the weather cap or its counterbalance arm in the closed position of the cap. The bumper further includes a dependent portion engageable by the counterbalance arm in the open position. The resilient bumper minimizes noise in both the open and closed positions of the cap.
