Post Cap Source is pleased to offer these maintenance-free, heavy-duty, long-lasting steel fence post caps in your choice of flat caps or caps with an ornamental ball finial. Steel post caps are to be used with steel posts and are not intended for use with aluminum fencing. These functional steel post caps come in varying styles and sizes to best meet your steel fencing needs and are easy to install and maintain while adding a classic, yet contemporary, look to your fence. Each uniform post cap can be easily mounted onto a post by slipping the cap over the post and tapping with a rubber mallet. The steel post caps are constructed of die-hard and durable steel components that are rust-resistant and will last for years. An excellent addition to an existing or newly-established steel or metal fencing project!
