Sizing for a
Lock Top damper
Masonry, brick or clay liners need to be measured by its INSIDE
measurement.
Older "clay" liners and newer ceramic liners will vary
in their inner and outer measurements.
Typically... a standard size 8x12 clay liner,
sometimes called a 9x13, will have an inner measurement of approximately
6 x 10 to as big as 7 x 11 1/2".
Measure and give us a call if
you would like help sizing for a Lock Top damper. |

Made to fit clay or terracotta flues

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 |

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.

Why buy Lyemance
brand Lock Top????
Take a look at the competition.
What is STAINLESS STEEL?
Stainless steel is a family of iron based alloys that must
contain at least 10.5% CHROMIUM (Cr). The presence of chromium creates an
invisible surface film that resists oxidation and makes the material "passive"
or corrosion resistant (i.e. "stainless").
Grading Stainless Steel.
As a percentage, the first number is the amount
of chromium that is contained in the stainless i.e. 18 is 18% chromium. The
second number is the amount of nickel i.e. 8 stands for 8% nickel. So 18/8 means
that this stainless steel contains 18% chromium and 8% nickel. This is a common
name for Type 304 Stainless. The higher the numbers the more corrosion
resistant the material. I wonder how much money was actually saved to make
these "other" caps?
