Handle/Valve Extender Kit

for use with the Chimney Balloon®

Handle/Valve Extender Kit

The HEK Handgrip/Valve Extender Kit is a way to get a further reach with your Chimney Balloon®. The HEK allows you many extra inches of reach and the valve handle is near the valve mouth. This is highly recommended if you have a damper that is high in the chimney or if you plan on installing your Chimney Balloon high in the chimney.

Rule of Thumb: If you can not easily touch the area you measured for your Chimney Balloon with your hand...you should buy an HEK Extender. It will make installation of the Chimney Balloon much easier.
