Description
A shaped cast cap for the top of 40 x 40mm square box section. A small square casting 41mm across and 51mm tall, with a stepped base, a deep waist and a pyramid top. It sits flush on the end of 40 x 40mm box and is welded all round, so a plain post finishes in a neat architectural cap. The price is for one cap, minimum order 10.

Why choose this cap
Flush with the post. The 41mm base lines up with the faces of 40 x 40mm box, so once welded and ground it looks like part of the post.
Proper finish. The stepped base, waist and pyramid top turn a cut box end into a finished railing or gate post.
Keeps water out. Welded on, it seals the top of the post against rain.
Where it is used
On railing posts, garden gate posts and fence posts made from 40 x 40mm square hollow section.

Fitting
Cut the post square and take off any burr. Sit the cap on the end, line its base up with the four faces of the post, tack each side and weld all round. Grind the weld flush, then prime with a metal primer and paint. We do not recommend hot-dip galvanising castings like this, as they can blister in the zinc bath; use a zinc-rich primer outdoors instead.
Frequently asked questions
Is the price for one cap?
Yes, one cap, with a minimum order of 10.
Does it slide over the post?
No. It is a flush cap that sits on top of 40 x 40mm box and is welded round the edge.
Why is there rust on it?
It is raw metal with no coating, so light surface rust can form in storage. It wire brushes off before priming.
