Flag pole balls (finials) are commonly made from metal or plastic. Listings typically show rustproof or aluminum options — including anodized aluminum finishes — and durable, corrosion-resistant plastic finishes.
Most ball finials use a 1/2" diameter screw thread. Several listings list a standard 1/2" thread for replacing toppers on 20–30 ft poles.
Common diameters range roughly from 2 11/16" to 3" (about 2.7–3 inches). The 3" and 2 11/16" sizes appear frequently across product options.
Ball toppers are commonly sized for residential and commercial poles in the 20–30 ft range. Some kits and telescoping poles are listed specifically for 20 ft or compatible with 20/25/30 ft sectional poles.
Listings show multiple spindle lengths; examples include 1 1/8" and 11/16". Different toppers use different spindle lengths to match pole heads or trucks, so check the spindle length when replacing a finial.
Common finishes and colors include glossy gold (often heavy-duty anodized aluminum) and black (corrosion-resistant plastic). Product listings typically describe either an anodized metal gold finish or a durable black plastic finish.
Trucks and toppers commonly list fit sizes near the 1 13/16" to 1 7/8" range (inner/outer diameter measurements are used in listings). Check the product fitment details to match your pole's diameter.
Finials typically screw on via a threaded spindle for simple, often tool-free installation. Several listings note spindle lengths that are long enough to accommodate integrated LED flagpole lights, but always confirm spindle length and lighting compatibility in the product details.
