    Staining is not required, it's your personal preference for how you want it to appear. Use a stain that is made for pressure treated wood.

        What is the size of the square of the fence cap at the bottom? It says 4x4 in description, but is the actual size 4.5? Thank you.

        Answer This Question

        The caps fit a nominal 4 x 4 post nicely, so probably a bit under 4" square inside.

        By|Apr 9, 2023

          It is 3 5/8 so it fits on a 4 x 4 post (which is actually 3.5 x 3.5 of course) with just a slight gap .  They have to be glued down.

                      Measure the newel. I think the cap would be too big for most newels I’ve seen. The caps have just a little extra space on a four by four. Your newel would have to be that size, 3.5 in.

                          I drilled small pilot holes to prevent cracking then screwed them in with 2 in coated screws, but I added a round post cap to the top (with a pilot hole) which hid the screws. Mike

                            Hello Betty, To attach post cap to the post, apply an exterior-grade construction adhesive to the underside of the post cap and place firmly on the post. You may read more about this is in the boxed-off Info & Guides section of the product page by clicking on the Installation Instructions link.

                                Reworked my deck and I chose these post caps for protection of the 4 x 4 post and they add a nice finished look. Bought 11 and I found no defects with any. Fit is good. If these don’t last I’ll update the review but as of now I am satisfied

                                  I really like the shape of these caps for my deck since you can place a drink on top. My only complaint is that one of the tops already split within a couple weeks of being outside on the post.

                                    Unfortunately I cannot reccomended this product as within 1 month of installation all but one have grown excessive amounts of mold on the surface and look awful. While none of the decking or railings, installed at the same time, show any signs of mold. This is very disappointing especially for such a small product that costs $10.00 each and is supposedly designed to be used outdoors.

                                    If you live in the Northeast you may get 2 years out of these. Not sure about other areas but all mine split right down the middle. The ones that were on when I bought the house were also split.
