Base Adapter by Aurora Deck Lighting
With Aurora Base Adapters, you can convert Aurora post caps and lights for a solid fit on unique-sized posts. They come in several colors to match the post caps and lights, with the same durable powder coated finish.
How do Aurora post caps and base adapters work?
To fit a standard size post cap or post cap light onto a unique size post, you simply switch out the original base on the Aurora post cap for an Aurora base adapter. The base adapter should be slightly larger than the post size.
Determining the post cap size needed:
Always measure the actual post that you're working with. Most standard 4 x 4 deck posts actually measure 3-1/2 in x 3-1/2 in. As a result, any post caps or post cap lights installed on standard wood deck posts should have a base opening of 3-5/8 in. The newer composites add a level of complexity as some 4 x 4 composite posts range from 3-1/2 in to 4-1/2 in.
Determining if a base adapter is needed:
Once a post size is determined, look on DecksDirect.com to see if the desired light or post cap is available in the size needed. If the light or post cap size you need is listed on the product page, only that product needs to be ordered. If the post cap is not available in the size needed, a post cap adapter may be added to the post cap to convert a post cap to a different size.
Choosing a base adapter size:
The base adapter you choose should be slightly larger than your post by 1/16 in to 1/4 in. This allows the cap to slide over the post during installation, and for the post material to expand and contract with temperature changes.
