What are the actual dimensions of standard 4x4 and 6x6 wood posts?

The precise outside dimensions of a standard 4x4 measures 3 ½″ x 3 ½″, and the 6x6 measures 5 ½″ x 5 ½″.

Will the stainless steel post caps of these decking products rust?

Yes. Corrosion and wear can strip away the hard oxide coating causing the steel to rust.

Can I use regular batteries in my solar lights?

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.

RDI Vinyl

What is vinyl made from?

Vinyl’s base ingredient is rigid PVC (polyvinyl chloride) modified to provide superior strength and ultraviolet resistance.

How strong is vinyl?

Our vinyl is impact modified for flexibility and durability. All RDI railing decking products meet or exceed the requirements for long-lasting durability and performance after installation.

Is vinyl safe?

Yes. Vinyl has a tough finish, retains virtually no moisture, has no taste, and is non-porous. Final RDI vinyl railing installations will hide all fasteners, leaving nothing but smooth surfaces and no sharp edges.

Will RDI vinyl railing turn yellow?

No. RDI vinyl contains 12 parts titanium dioxide which prevents ultraviolet degradation.

Are RDI vinyl railing kits reinforced in any way?

All our vinyl railing kits are reinforced top and bottom with aluminum extrusions that are specifically engineered for the best performance possible.

Can one railing kit be split evenly in half?

Kits can be cut down to any dimension and, with an additional bracket kit, can become two complete railing sections. Cutting a kit evenly in half usually will not work with symmetrical end spacing.

RDI / Metal Works / Excalibur

What gauge steel is the RDI Metal Works system?

The rails are 14 gauge, posts are 13 gauge, and balusters are 16 gauge steel.

What is the baluster size and spacing for a level rail panel?

RDI Metal Works Excalibur has ⅝” (.625) inch square metal balusters with 3 ⅞” (3.850) inch spacing, measured between the inside faces of two adjacent balusters.

Is the baluster spacing the same for the stair rail panel?

Yes, but only when the stair section is level (0 degrees).

What is included in a level bracket kit?

  • 4 brackets

  • 4 bracket covers

  • Installation hardware

What is included in a stair / level angle bracket kit?

  • 4 brackets

  • Installation hardware

How do I mount an RDI Metal Works steel post?

You must use proper fasteners during installation and check local building codes for requirements. Each post includes two shims which should be used for leveling the post during installation. RDI Metal Works posts include a 4”x4” bottom steel flange which is ¼” inches thick. The flange is manufactured to accept ⅜” (.375) diameter fasteners.



What is the run time on the solar light?
The run time will vary based on the season. During the summer months, the solar light will run for up to 14 hours. During the winter months, the shorter daylight hours, as well as cloudy days, will reduce the run time to approximately 3-6 hours. 

How long will the Solar lights last?
The LED bulbs are designed to last a lifetime, as is the solar collector. These are of the highest quality and latest technology available today. The batteries are 1.5V NiCad batteries. These will last approximately 1000 cycles, or roughly three years. Batteries are warranted for one year. Replacements can be purchased locally. 

My solar light will not light up?
The most common issue is the battery. It takes up to three weeks for a new solar unit to cycle to full capacity. Winter months will effect this cycle time as well, if installed in the middle of winter. To test a solar unit, remove the NiCad batteries, and install AA alkaline batteries. Cover the entire solar collector to test the unit. If the unit lights up, replace the NiCad batteries.

Low Voltage:

How many lights can I install on a transformer?
Up to 50 lights. See transformer section. For further detail, read the transformer instruction sheet included with the transformer. 

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 parts store. 

Can a 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 Decklights 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 appear dimmer. 

Can 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 green 

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.
