A mechanical damper that responds to heat.
TipTopTemp™ is a self adjusting mechanical top damper for grills and smokers. The TipTopTemp damper changes the flue airflow powered by the grill's heat-instead of using a powered fan forcing air to the coals.
Heat moves the bimetal element.
The TipTopTemp bimetal coil moves as its temperature changes. That movement is connected to the damper, so a temperature change produces a physical change in the flue opening.
As the grill or smoker warms and cools, the mechanism moves with it. The goal is not to create heat with electronics, but to make small airflow corrections at the top vent using the heat that is already there.

The movement is slow by design.
Watch the damper move as temperature changes. The movement is gradual, so the video starts at 2× speed. Switch to normal speed or 4× speed whenever you like.
Materials, dimensions, and construction.
The TipTopTemp is made from heavy gauge plated steel with a hardwood adjustment knob. The controller is the same across packages; mounting accessories vary by grill and vent style.

How to use it on your grill.
