Sizing for an RS Adaptor

Single wall, liners and Class A insulated flue pipe need to be measured by its INSIDE measurement.

Typically... newer standard size insulated flue pipe will have a 1" thick wall.
Older insulated flue pipes will vary in their outer measurements.

Measure and give us a call if you would like help sizing for an RS Adaptor.

CAUTION: A custom Air Cooled Adaptor must be used for Air Cooled Pipe. 
DO NOT attempt to use a standard RS Adaptor with air cooled pipe.

Air cooled double and triple wall flue systems need to be measured by their INSIDE measurement.

Typically... the inner pipe will be a "full" inch measurement...
IE... 8" not 7 3/4" or 10" not 10 1/4"
... the larger outer pipe will vary in size depending on the air space between the pipes and manufacturers design..

The inner and outer pipe need to be the same height for proper installation of an RS Adaptor.

Need extra help?  Measure and e-mail us a picture....

If the inner pipe is higher the outer pipe you will need to cut the pipe to the same height as the outer.
Note: look for any "extension" of pipe that can be removed to avoid cutting.
If the inner pipe is lower than the outer... a small section of pipe may need to be installed.

Lock-Top's rubber gasket seals tightly like a storm door for your fireplace, and keeps heating and cooling dollars where they should your home.

Lock-Top mounts on top of your chimney to keep out animals and rain.

Lock-Top easily operates from inside your firebox and seals tight every time you close it—eliminating any draft.

Cast-iron plate and frame do not seal tightly, allowing energy dollars to escape.

Traditional dampers are located in the "throat" of a fireplace. They are made of cast-iron and are housed in a low-tech frame work.

These cast-iron dampers do not seal well—they have a leaky, rough, metal-to-metal seal.

Recent lab studies have shown that even a new throat damper can leak up to $200 of heating and cooling a year. Imagine how much energy an old, rusted out damper leaks!

The Lock Top damper seals with a rubber gasket, not metal to metal like your current damper. A Lock-Top Damper seals tight, so virtually no air, and thus no heat or air conditioning gets lost up your chimney.

The Lock Top also eliminates downdrafts, seals out rain which can deteriorate the inside of your chimney, and prevents entry by pests like squirrels, raccoons, and nesting birds.

The Lyemance Lock Top Chimney Damper mounts on top of your chimney


Lyemance Lock Top Chimney Damper Gasket

Lyemance Chimney Damper


A cable drops down your flue and attaches to a handle which mounts where you can reach it for convenient opening and closing.

Superior stainless steel and cast-aluminum construction equal a lifetime warranty
The Lock-Top Damper is made of cast-aluminum and stainless steel, precision fitted with our special silicone rubber gasket. These high-quality materials add up to a factory lifetime warranty for you.

A nice installation with a custom Air Cooled Pipe Adaptor
and Lock Top II damper/cap.....
