4 Inch Painted Black Aluminum Ball Flagpole Ornament 1/2 Inch-13NC Spindle Thread 330022

4 Inch Painted Black Flagpole Ball Ornament

A 4 inch painted black ball ornament for the top of an outdoor flagpole, with 1/2 Inch-13NC spindle threading. Part number 330022, model SB104.

Will this size fit my flagpole?

Match the ball to the BUTT DIAMETER of your pole, not its height. The butt diameter is the width of the pole at the bottom, where it comes out of the ground or the shoe. The accepted rule across the flagpole trade is that the ball diameter should equal the butt diameter, and this 4 inch ball is sized for a 4 inch butt diameter — common on 20 to 25 foot residential and light commercial poles.

If you are not sure, measure across the base of the pole with a tape or a set of calipers. Getting it right matters visually — a ball much smaller than the pole looks like a knob, and one much larger looks top-heavy.

Will it thread onto my pole?

This ornament screws into the flagpole truck, the fitting at the very top of the pole, on 1/2 Inch-13NC threading. Across the industry, 2 through 8 inch balls use 1/2 Inch-13NC and 10 and 12 inch balls use 5/8 Inch-11NC, so if you are replacing a ball of the same diameter the thread will almost always match. Unscrew the old ornament and check the stud before you order if you want to be certain.

If your pole has no truck drilled for an ornament, you will need a pole top adapter as well. The spindle is long enough to take a disc-style solar or LED flagpole light between the truck and the ball if you light your flag at night.

About the painted black finish

Black is a baked painted finish over spun aluminum. It is the sharpest looking of the painted options against a light building and it is the usual choice on black anodized poles.

Best for black poles, and a high-contrast look against light stone or render.
