50mm Diameter Round Post Cap
Strong and durable post caps, internal fit. Suitable for aluminium or steel sign posts that require capping. Post caps are very important for exterior installations as they stop rain water filling the posts and causing steel posts to rust.

Good afternoon mark

We have never sold 40mm diameter post caps – This is a standard product the outside diamater of the top of the cap is 50mm with ribs down the length to suit varing thicknesses of wall on the post.
Please could you check the diameter of the post you are wanting it to fix to along with the wall thickness and please give us a call with this information to see if we can help
