ARE YOU ORDERING THE CORRECT SIZE POST CAP? We list the opening size of the post cap. The size you select should measure equal to or slightly larger than your post in order to slide into place over the post. Example a 6x6 post may actually be a 5.5" x 5.5" post. Please contact us if you’re unsure which size you’ll need

Nantucket Post Caps are sized according to the actual physical measurement of your post. All caps are made 1/8" larger on the opening than the actual post size you specify. For example, if your 4x4 standard post truly measures 3-1/2" x 3-1/2", choose that size and your cap will come with an inside measurement of 3-5/8" x 3-5/8" to allow it to slip over your post.

  1. Copper post caps review by Christoph on 4/15/2021
    Overall Product Rating

    Beautiful product! I had searched locally for copper caps to fit full sized 6x6 cedar timbers and could not find anything. Most were plastic not copper. These caps are fantastic. Well constructed and beautiful true copper. Fair pricing too. The arrived very quickly and we packed extremely well. I will definitely use again on another project.

  2. Great build quality review by Luke on 4/7/2021

    These were exactly what I was looking for. The build quality seems good, sonic expect them to last a while

  3. Excellent product review by Gwen on 11/18/2020

    The Cambridge Copper Post Cap is very nicely made. It was the top for a custom stone pillar light. I received it in a timely manner.
    I would order it again if I have another pillar light made.

  4. Excelent Quality and Perfect Fit review by David on 8/13/2019
    Overall Product Rating

    I purchased 4 of these for the posts on a pair of trellises in my yard. They look great and fit perfectly. The copper tops add a nice touch. They arrived quickly and were packaged very well to avoid damage. I would highly recommend these and The Deck Store.

  5. Think recycled cardboard or paper review by Mark on 4/10/2019
    Overall Product Rating

    I'm withholding a star due to all the single-use, non-recyclable plastic that was used in the packing of the boxes, but otherwise the odd-sized caps I custom ordered worked just fine.
