Replace old broken iron fence spires, aka finials or toppers, or just improve your existing iron fence. These are new never used, (100 each in package), made of injection molded polypropylene high impact plastic. See photo to confirm you are ordering the correct size for your application; these are also available in 5/8 and 3/4-inch sizes. For Halloween graveyard fence props, this size will not fit 1/2-inch schedule 40 PVC, or 1/2-inch CPVC tubing. See other sizes for those applications. Easy to install with included installation instructions by using a soft hammer.
