Below are some frequently
asked questions about our post caps and other accessories. Read on to learn more about our
products' characteristics, installation, fasteners, warranty, and care and cleaning.
Care and Cleaning
What are the inside dimensions of your post caps?
Our post caps come in many sizes, but the most common sizes are 4 x 4 and 6 x 6, which are
made to fit a nominal 4 x 4 or 6 x 6 post. The inside dimensions of the nominal 4 x 4
measures 3-5/8", and the inside dimensions of the nominal 6 x 6 measures 5-5/8".
We carry a limited selection of other opening sizes, such as 4-1/8", 4-5/8",
4-7/8", 5-3/16", and 6-1/8". In addition, we have a 4 x 6 post cap (with
inside dimensions of 3-5/8" x 5-5/8") in two, all-wood styles: Newport High
Pyramid and Newport Classic. We also offer as 8 x 8 Copper-Topped cap with an opening size
of 7-5/8" and a 10 x 10 cap with an opening size of 9-5/8". All of these special
sizes are available in cedar. Our 4 x 6 post caps are also available in redwood.
Will my stainless steel post caps rust?
Stainless steel is an alloy of iron that contains more then 10% chromium. Its hard oxide
coating makes it resistant to stains. If corrosion or wear strips away this coating,
however, the steel will rust. Stainless steel, therefore, should be cleaned periodically.
One way to clean stainless steel is to use a mixture of vinegar and club soda. Additional
cleaning suggestions can be found on the Internet.
Will the brass post caps tarnish?
Our brass post caps are a true metal brassan alloy of copper and zinc. They are
protected by a thin layer of clear coating. This coating, however, breaks down over time,
exposing the brass. Once moisture reaches the brass, it begins to tarnish. A periodic
reapplication of the clear coating will slow this process.

What preservative is used to protect our pressure-treated
wood post caps?
Our wood post caps are protected by CA-B (Copper Azole Type B), an EPA-registered
pesticide containing copper and azole compounds to protect it from termite attack and
decay. For more information, refer to the Copper Azole Safe
What type of fasteners (and other metal products)
should be used with CA-B pressure-treated wood products?Hot-Dip Galvanized fasteners are recommended for use with CA-B treated
wood. Stainless Steel fasteners are also excellent for this use. For more information on
fasteners, refer to Fasteners for CA-B Pressure Treated
How bright is the solar post cap light?
The solar post cap light provides an ambient, non-task-oriented light.
Where can I purchase replacement LED light bulbs?
The LED bulbs are part of the whole solar cell component and are not designed to be
replaced. The LED bulbs have an average life of 10 years, with a normal usage of 6-8 hours
What kind of replacement batteries should I buy for
the solar post cap light?
If the rechargeable batteries provided will no longer recharge, they can be replaced with
any AA rechargeable batteries. The life depends on the quality of the batteries purchased.
Note: We are unable to
guarantee the lifespan of the courtesy batteries that are shipped with
the caps. Replacements can be purchased locally.

How long will the rechargeable batteries provided
with the solar post cap last?
The rechargeable batteries should last approximately one year.
Can I use regular, non-rechargeable batteries in the
solar post cap light?
No, the solar post cap light is designed to be used with rechargeable batteries. If
regular batteries are used in the sun, they will destroy the solar collector.
How long is the life of the LED light bulbs?
With a normal usage of 6-8 hours per day, the LED bulbs should last an average of 10
years. Some can be replaced, many can't.
What is the metal underneath the post caps with the
The base of our powder-coated post caps is made of stainless steel.
Top of Page
What is powder-coating?
Our white, green, real patina, pewter and black post caps are all treated with
powder-coating. Powder-coating is a dry finishing process in which finely ground particles
of pigment and resin are electrostatically charged and sprayed onto an electrically
grounded post cap. The charged powder particles adhere to the grounded post cap until they
melt and fuse into a smooth coating in the curing oven. The result is a uniform, durable,
high-quality finish that is also environmentally friendly.
What does dentil mean?
Dentil refers to the wood frame of the post cap and is one of a series of
closely spaced, rectangular blocks that form a tooth-like, dentil molding on the frame of
the post cap. Dentil molding, usually found on rooflines of buildings, can also form a
decorative band on any fixture.
What does patina mean?
Patina refers to the natural weathering of copper due to airborne sulfur
compounds, which gradually change coppers surface color. The resulting color, called
a patina, depends on location and climate. Salt, moisture, sunlight, ultra-violet rays and
pollution can affect the final color. In general, copper progresses from a natural salmon
to shades of russet brown and gray, and then finally to a blue-green or gray-green patina

What is a post skirt?
A post skirt is a trim molding for the base of a post. Post skirts are available in 4 x 4
and 6 x 6 sizes, three styles, and three wood species: pressure-treated pine, cedar, and
redwood. They can be used alone or in combination. Our post skirts are cut to size, with
three sides pre-joined. The fourth side can be easily slipped into place and attached with
finish nails, staples, or exterior-grade construction adhesive.

How do I attach the post cap to the post?
We recommend using an exterior-grade construction adhesive to adhere the cap to the post.
Apply the adhesive liberally to the inside of the cap and place the cap firmly over
the top of the post. If you prefer to use Brad nails, be sure to pre-drill all nail holes
to avoid splitting. For more information, refer to the installation
How do I attach the solar post cap light to my post?
To attach our solar post cap light to a post, apply an exterior-grade construction
adhesive to the inside edge of the molding at the bottom of the light, and then place the
light firmly onto the post. Not all solar caps can be permanently
mounted to the post, some need to be removed to replace the batteries.
See the installation instructions provided with your caps for individual
instructions, for general information, refer to the installation
Should the switch on the solar post cap light be in
the ON or OFF position to charge the batteries?
Your solar post cap light will need 24-48 hours of sunlight, with the switch in the OFF
position, to fully charge. Once the batteries are fully charged, you can leave the switch
in the ON position. The solar collector will charge the batteries during the daylight
hours, and the batteries will power the light during darkness. If your light dims, try
recharging the batteries again by giving the light 24-48 hours of sunlight with the switch
in the OFF position.
Should I remove the thin, clear plastic film over the
top of the solar collector on the solar post cap light?
Yes, the clear plastic cover is meant to protect the solar collector during shipping.

Care and Cleaning
Will my copper post caps remain a shiny copper color?
Our copper, stainless steel, and brass post caps come with a thin clear coating designed
to protect them before and during installation. Once they are exposed to the elements,
however, the suns ultraviolet rays begin to break down this coating, exposing the
metal underneath. The copper caps, therefore, will gradually progress from a natural
salmon to shades of russet brown and gray, and then finally to a blue-green or gray-green
patina. Depending on climate, pollution, and sun exposure, this process can begin anywhere
from six months to two years.
How do I keep my copper post cap from turning color?
There is no permanent protection system that will keep copper from weathering. There are
clear coatings that will provide short-term protection for exterior applications and
longer-term protection for interior applications. The copper color can be prolonged by
periodically re-applying a clear spray lacquer before oxidization begins.
Can I speed up the patina process on my copper post
You can remove the thin layer of clear coating by using either mineral spirits or acetone.
Once the copper is exposed, the patina process can be hastened by spraying the copper with
a mixture of lemon juice and water and keeping the cap in a damp place.

Do I need to apply a finish to my wood post caps?
As with all wood products, we recommend that you coat the wood portion of our post caps
with a high-quality, exterior-grade wood preservative to protect the woods natural
beauty and ensure a lifetime of enjoyment. Apply the finish to all wood areas, including
the underside of the cap before installation. Consult your local paint supplier for the
best product to use in your area.
Should I allow my treated wood post caps to
"season" outdoors before I apply a protective finish?
No, our treated wood post caps are kiln-dried and do not require a drying period. We
recommend applying a protective finish immediately.

Low Voltage Wiring
How many lights
can I install on a transformer?
Up to 50 lights. Read your transformer instruction sheet included with
your transformer for recommendations. The transformer dictates the
amount of lights it will support.
What type of bulb is used,
and where do I get replacements?
The bulb is a
standard automotive brake light bulb, and can be purchased at any auto
dimmer switch be used?
Dimmer switches are not effective on low voltage lighting.
Can the light output be
reduced on the low voltage light?
A 7.5 watt bulb is available to reduce the light output if desired.
Some lights appear dimmer
than others, what do I do?
This is a result of wiring issues. Primary due to longer distances from
the transformer (200 or more feet). There are several different wiring
schemes to address and/or correct this. Please refer to the transformer
instruction manual to correct.
I have low voltage
landscape lighting; can I add deck lights to this?
Generally, the answer is no. It is best to start from scratch, for two
reasons: First, the transformer likely has less wattage output than is
necessary for the Aurora Deck lights. In addition, landscape lighting
usually uses 18-gauge wire, which is too light for the Aurora Deck Light
product. Using this will cause a drop in wattage, making the lights
I change the glass style in the light?
Yes, glass can be purchased separately to change between the styles.
This includes new Tiffany Opalescent Glass in red, white, blue, and
Can I put
the lights on an inside switch?
Yes. To do so, the outlet that the transformer plugs into must be wired
to the desired switch. The transformer is then placed in "manual mode",
operated by the light switch.
