Standard Single-Pulley Spindle-Style Revolving Flagpole Truck

The truck is the assembly at the very top of a flagpole — the housing that holds the pulley and supports the ornament (the ball or eagle on top). When your halyard frays, the pulley wears out, or your flag keeps wrapping around the pole, the truck is usually the part that needs replacing.

This is our Standard spindle-style revolving truck — the value option for customers who need a reliable replacement at a budget-friendly price. Cast aluminum housing, cast nylon pulley wheel, self-lubricating ball bearings. It does the same job as the Deluxe with a tradeoff in long-term pulley wear (more on that below).

Critical Sizing — Read Before Ordering

Two things to verify on your pole:

1. The pole top has a threaded female fitting — look down into the top of the pole. You should see internal threads. If the top is solid, capped, or open with no threads, you have a different style of pole top (see options below).
2. The threading is 1.25" NPT (National Pipe Thread). This is the standard size on most residential and light commercial in-ground poles, but commercial manufacturers occasionally use proprietary threading. If you can't confirm, contact us with the pole's make and model.

The truck fits poles with an outside top diameter of up to 3.5". The pole's OD doesn't need to match the truck — the truck threads in, it doesn't clamp on.

Two possible scenarios if your pole top doesn't have the right fitting:

If you're not sure which scenario you're in, contact us with photos of your pole top and we'll help identify what you have and what you need.

Spindle-Style vs. Cap-Style — Which Do You Have?

This is the most common point of confusion when ordering a replacement truck. The two designs aren't interchangeable, and pole top design dictates which one you need.

If your halyard runs inside the pole rather than along the outside, you have an internal halyard system, which uses a different truck design entirely. Internal halyard systems vary by pole manufacturer — contact us with your pole make and model.

Standard vs. Deluxe — What's the Difference?

Two things separate the Standard from our Deluxe Single-Pulley Revolving Truck:

Pulley wheel material. The Standard uses a 1.5" cast nylon pulley. The Deluxe uses a machined aluminum pulley of the same size. Cast nylon is durable and works well in normal residential conditions, but over the long haul it can deform, develop wear grooves, or eventually crack — aluminum doesn't.

Bearing grade. Both use self-lubricating ball bearings, but the Deluxe uses a higher-grade sealed assembly rated for continuous outdoor rotation under load. The Standard's bearings are perfectly adequate for most residential use; the Deluxe's are overbuilt for harsher conditions or longer service intervals.

For a typical residential pole flying a single 3x5 flag, the Standard is the practical choice. For a high-traffic flag, a coastal or high-wind location, or maximum overall longevity, step up to the Deluxe Single-Pulley Revolving Truck.

What Pairs Well

Installation Overview

Replacing a truck is a straightforward job, provided you can safely access the top of the pole.

You'll need

• Safe overhead access to the pole top — typically a bucket truck or lift
• A pipe wrench for the truck spindle
• Thread sealant or PTFE tape rated for outdoor use
• A second person on the ground to manage the halyard
• A new halyard, ornament, cleat, and snaps if you're refreshing the whole top assembly

Procedure

1. Lower and remove the flag.
2. Untie the halyard from the cleat at the base of the pole. Pull one end up and through the old truck's pulley to free the rope.
3. Remove the existing truck assembly from the pole.
4. Inspect the female fitting on the pole top — clean out any debris, old sealant, or corrosion before installing the new truck.
5. Apply thread sealant or PTFE tape to the new truck's 1.25" NPT spindle threads.
6. Thread the new truck into the pole top. Hand-tighten first, then snug with a pipe wrench. Don't overtighten — NPT threads seal by interference, and excess force can crack a cast housing.
7. Thread your halyard through the new pulley and tie off at the cleat.
8. Thread a new ornament into the 1/2"-13NC top drilling and secure with the included 1/4"-20NC stainless set screw.

Made in the USA

This truck is cast and assembled in the United States. We carry it specifically because the build quality holds up against imported alternatives that wear bearings within a season or two — even at the value tier. Read more about our commitment to American-made products.

Frequently Asked Questions

What's a spindle-style truck and how does it differ from cap-style?

A spindle-style truck (this one) has a threaded base that screws into a female fitting inside the top of the pole. A cap-style truck slides over the outside of the pole and clamps with set screws. The two designs are not interchangeable — your pole's top construction determines which one you need. If your pole has a tapered top with no threaded fitting, you need cap-style.

How do I know if my pole has a 1.25" NPT female fitting?

Look down into the top of the pole. If you see internal threads, you have a threaded fitting. 1.25" NPT is the standard size on most residential and light commercial in-ground poles. If you can't confirm, contact us with the pole's make and model and we'll check against our records. If your pole has no fitting at all, a pole top adapter may convert it.

Does the truck rotate a full 360 degrees?

No, and it shouldn't — full 360° rotation would mean the halyard isn't anchored, which would defeat the purpose of being able to raise and lower the flag. The truck rotates roughly 270° before the halyard reaches its tether point at the cleat. That range of motion is what prevents the flag from wrapping in normal wind, and if it does briefly wrap during a sudden wind shift, the truck rotates back the other way to unwrap itself rather than locking up. This is the intended design behavior, not a defect.

What halyard size does this truck use?

The pulley is rated for halyard up to 5/16" diameter. Larger diameters won't seat properly in the pulley groove. Smaller diameters will work but may slip. We recommend replacing the halyard at the same time as the truck.

What ornaments fit this truck?

Any standard ornament with 1/2"-13NC spindle threading — that includes most ball finials and eagle ornaments designed for in-ground flagpoles. The included set screw secures the ornament so it won't unthread in wind.

What's the difference between this and the Deluxe Single-Pulley Revolving Truck?

The Deluxe uses a machined aluminum pulley wheel and a higher-grade sealed bearing assembly. The Standard uses a cast nylon pulley and standard self-lubricating bearings. Both are revolving, both fit the same pole configuration, both are made in the USA. For typical residential use the Standard is the practical choice; for harsh environments or maximum overall longevity, step up to the Deluxe.

Can I install this myself?

Yes, with the right equipment. You'll need safe access to the top of the pole (typically a bucket truck or lift), a pipe wrench, thread sealant or PTFE tape, and a helper on the ground.
