Do copper post caps turn green?

Copper post caps are one of the most popular choices for deck and fence post caps. They are attractive and durable, but one downside is that they can turn green over time. This is because copper is a reactive metal and will start to form a patina when exposed to the elements. The patina is a thin layer of greenish-blue copper oxide that forms on the surface of the metal. While some people like the look of a patina, others prefer their copper to stay shiny and new-looking.

(32 Pack) New Wood Fence Post Black Caps 4X4 (3 5/8") for Pressure Treated Wood Made in USA Review:


Our old fence was replaced, but the post caps were preserved. We used these to extend the old fence by a few more feet. The new caps completely match the previous caps, and they are well-made. My husband appreciated that the cap had a hole already drilled into it so he could fasten it with a screw of his choice. (Please note that the purchase does not contain any screws or nails.)



5.5" x 5.5" Heavy Duty Aluminium Pyramid Post Cap for Wood Posts - Black Review:


We are finishing up a front porch project and struggled to find suitable post caps to cover our 6x6 posts. Some of the available caps are ridiculously pricey or constructed for a true 6x6 rather than a nominal 6x6, and plastic looks poor and fades (which is actually 5.5x5.5). We made the decision to test these, and I was VERY pleasantly surprised. They properly fit our posts (5.5x5.5), are sturdy, and look great. They're a tad pricy, but I'm really enjoying them so far! They are very firmly mounted and wobble-free because mounting screws are included with them. One piece of advice for anyone who purchases these: pre-drill your holes because the screws aren't really pointed enough to self-drill. Additionally, if the tops of your posts aren't level, doing this will ensure that they are level on your posts. Your best bet is to position them precisely where you want, pre-drill (I used a 5/32" bit), get the screws in both sides, then tighten them down. If you screw one side down tightly, it will raise the adjacent side up. Overall, I'd say these are excellent!



Durable White PVC Vinyl External Pyramid Post Cap for A True 5 Inch x 5 Inch Post | Single Pack | AWCP-EXT-5 Review:


When I bought my new home, my fence's caps were missing. Home centers around didn't have any basic caps like this for some reason. had a variety of wooden or solar-powered lights. The only issue is that I now need to pressure wash the remainder of the fence because it contrasts with the brand-new, spotless tops and looks even dirtier.



The Hillman Group 45632 5/8-Inch Axle Cap Nut, 8-Pack Review:


It was necessary to give a large drain snake wheels. purchased a 10" wheel from Harbor Freight and a 5/8" rod from Home Depot. The axle was welded in place, and the wheels were then securely fastened to the axle using washers. To begin, position the cap over the axle and firmly tap it with a hammer. appears to be stable.



WEATHERABLES Durable White PVC Vinyl External Pyramid Post Cap for A True 4 Inch x 4 Inch Post | Single Pack | AWCP-EXT-4 Review:


This cap was actually utilized at the END of the post. In order to help the wood last longer, I utilized a sleeve on a pressure-treated redwood 4X4 with this on the BOTTOM. This method didn't require any concrete on my part. Much simpler and less expensive. Zero mess I only required a couple of deck screws to secure it while I sunk the post. It would have looked fantastic on top as well, but I chose a solar-lit cap instead because it was difficult to see my driveway at night in the forest. Helpful is the top light. However, this cap would have looked equally good on top.



JSP Manufacturing 16 Pack Fence Post Plastic Black Caps 4X4 (3 5/8") Pressure Treated Wood Made in USA Review:


Post caps that are only functional and not at all fancy 16 PACK Fence 4X4 (3 5/8") Pressure Treated Wood Post Plastic Black Caps made in the USA that fit exactly. Simply remove the tiny plastic stem from the cap, apply sealant to the post tops and interior, then screw the caps back on. No screws or nails are required.

JSP Manufacturing Plastic New Fence Post Black Caps 4X4 (3 5/8") Pressure Treated Wood Made in USA MULITPACK Wholesale Bulk Pricing Review:


These do, in fact, fit snugly on modern "4x4s" (I put that in quotations as we all know they are NOT 4" by 4" anymore). The ones I previously bought from HD were too big, but these fit GREAT!These will last the test of time because the plastic is incredibly thick. The tops of my 4x4s suffered some damage because I had to smash them into the brackets, which made me worry about potential water problems down the road. Problem fixed with one of these and some silicone!As any time you have a hole you have potential to leak, I like these over some of the others that you attach with a nail or screw. This potential failure is avoided by these being sturdy. They're excellent.



Pylex 13048 44 Post Base, Black Review:


liked this stuff a lot. It looks lovely on our deck and front porch, as the picture I included shows. These are what we used to fasten the 4x4s to the deck, and they really make it pop. They are well-made and dependable. According to earlier reviews, you might need to trim some of the 4x4's sides to fit in these bases, however that wasn't a problem. I wholeheartedly endorse these for anyone looking to utilize them, but I wish you would provide a 6x6 snap-together version. Considering that I haven't found anything I like yet, I would buy them for my front porch.



6x6 Post Cap - (Nominal) Black Flat Top - 10 Year Warranty! Review:


Although I wasn't sure how this product would turn out, I decided to buy post caps because I was too lazy to make my own. The conventional wood caps that you buy don't interest me because they only last a few years before they start to crack and deteriorate. Since there was no other means to match my standard of quality historically, I created my own out of 1 1/2 thick treated material.These have a genius two-piece design. To join the bottom half to the top of your post, which allows you to center them perfectly, just drive in two screws, there are a few tabs on the lower piece. You then snap on the top, and you're done. I could not possibly have built and installed these for this cost.These are made of automotive-grade plastic and I have no doubt that they won't shatter or disintegrate long after I am gone.Avoid second-guessing yourself and just get them; you won't regret it.Enjoy your day, Jeff



4x4 Post Point Cap - Solid Copper (3-1/2" x 3-1/2") Review:


Instead of those items that were shoddily put together from lesser materials like copper coated plastic and its ilk, they were genuinely fashioned of sleek, modern, solid copper that was carefully moulded to shape.Invest in this product if you want something that will grow in value over time. You'll know you made the right decision once you have them in your hands and feel their weight!If I had any criticism at all, it would be that I wish there were two nail holes so that the cap could be fastened with copper nails. Of course, I could still do that, but the installation would be real "turn-key."These genuine copper crowns on my cedar box garden are beautiful. Although I previously knew the nails and drill holes weren't part of the design, I'm looking forward to the stunning patinas that will develop on the red wood and the verdigris that will appear on the copper adornments.
