Hi Jake, the depth of the cap is approximately 1-1/8".
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.
Tague, this profile of post cap will only be offered in a 4-inch by 4-inch size.
The caps fit a nominal 4 x 4 post nicely, so probably a bit under 4" square inside.
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.
Travis, Yes the outside of the base is 4 1/2 inches. The widest part of the base is 5.31 inches. The inside of the base dimensions fit a a 4 in x 4 in wood fence post.
I don't see why not.
I don’t see why you couldn’t
Yes as long as the wood is not treated.
Susan, These are designed to fit a 4 in x 4 in. wood fence post.
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.
Hudly, The square on the top of the post cap is 3 in x 3 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.
Hello Lane, The cap components are made outside the U.S., but are assembled here in the U.S.
