Lighted Post Cap Fit Guide

"Will my lighted post cap fit my deck post?"

That is a good question and we get it a lot at The Deck Store.

The simple answer is: it depends!

Here's Why! Manufacturers want you to use their products. So if they were to make a post, where only their cap would fit, you would have to buy their product. Right! Selecting which one will fit each other is nearly impossible, of course a larger cap will fit a smaller post, but it may be too loose. Some manufacturers will change the shape of their post to limit which caps fit. One technique they use is to put a radius or diagonal corner on the cap and sleeve, so even if the post is identical in size, the shape prevents other caps from fitting. Here's one additional challenge, Color! Need I say more?

It should be no surprise that some of the newer entries in to this market are making caps that can fit multiple size posts. It is also well known that some manufacturers don't really make their own caps or lights at all, someone else does. If we were to mention specific brands that fit Major Brands here we would likely lose the ability to provide them. But we do offer caps on our site from manufacturers that provide not only the caps, but other lighting supplies, balusters, etc.  If your looking to fit a Name brand post, consider the more generic lower priced options. LMT is an example of a manufacturer that produces products for multiple companies. We carry many of their items under The Deck Store name, maybe you'll recognize them. 

The Fortress Accent Post Cap is a name brand that is designed to fit multiple size posts too.  The cap is made of a very heavy and durable metal and the colors are selected to compliment your existing post sleeve. These caps go well with wood, composite, and metal post sleeves.
