An anchor kit is the part buyers forget until the pole is already loose or the hoop needs to move to a new spot in the driveway. It’s the ground-mounted plate and hinge the pole actually bolts into — not the concrete itself, but the hardware that lets that concrete hold the pole rigid for years, or let it tip down for storage. We compared the kits that fit the widest range of in-ground systems and hold up under real play.

1. Goalrilla 9-Inch Anchor Kit — Best for Goalrilla
Goalrilla 9-Inch Anchor Kit
- 9-inch base plate matched to Goalrilla's 4x4-inch, 10-gauge steel pole for a flush, no-slack fit.
- Hinge lets the whole pole tip down to ground level for off-season storage or moving through a gate.
- Sold directly by Goalrilla, so hardware and torque specs match the pole exactly.
- Priced for a single brand — a universal kit costs less if the hoop isn't a Goalrilla.
The 9-inch plate is the reason this kit tops the list for Goalrilla owners — it’s built for the brand’s heaviest residential poles, where a narrower 7-inch base would be under-sized. Setting the footing before the pole goes in? Try Amazon Prime free for 30 days to get the anchor kit, a pole pad, and a replacement net delivered in two days. Pour the footing at least a couple of feet from any existing slab, per our install guide, so the anchor has its own undisturbed concrete to grip.
2. Silverback 7-Inch Anchor Kit — Best for Silverback/Goaliath
Silverback 7-Inch Anchor Kit
- Matches the narrower pole base used across Silverback and Goaliath in-ground systems.
- Same tip-down hinge design as the Goalrilla kit, just sized for a lighter pole.
- Costs less than the Goalrilla kit, in line with the smaller base plate.
- Won't fit a Goalrilla pole — the 7-inch bolt pattern is too narrow for the brand's 9-inch base.
If the hoop already in the driveway is a Silverback SBX 54 or a Goaliath in-ground model, this kit’s 7-inch base is the correct match rather than an oversized 9-inch plate meant for a heavier Goalrilla pole. Fit matters here more than most accessories — an anchor sized for the wrong pole leaves play in the base that no amount of tightening fixes.
3. Progoal 9-Inch Anchor Kit — Best Universal/Budget
Progoal 9-Inch Anchor Kit
- Bolts to a standard pattern rather than a single brand's proprietary base, so it fits most residential in-ground poles.
- A fraction of the price of the brand-name Goalrilla and Silverback kits.
- Designed for easy relocation — unbolt and move the hoop to a different footing without repouring concrete.
- Lighter-gauge steel than the brand-specific kits, so it's a better fit for lighter poles than a full commercial-grade rig.
For a Spalding, Lifetime, or off-brand in-ground pole that doesn’t have a dedicated anchor kit from the manufacturer, a universal kit like this one is the practical choice — the standard bolt pattern fits far more poles than either brand-specific option above, at roughly a quarter of the price.
How to choose an anchor kit
- Match the base size to the pole, not just the brand: A 9-inch plate under-supports nothing, but a 7-inch plate on a pole rated for 9 inches can leave the base under-braced. Check the pole’s own spec sheet if the brand isn’t Goalrilla or Silverback.
- Decide if relocation matters: Every kit here has a tip-down hinge, but universal kits are typically the easiest to fully unbolt and move to a new footing later.
- Footing depth still comes first: The anchor is only as rigid as the concrete it’s set in — see our install guide for footing depth and cure time by pole weight.
- Pad the pole once it’s set: A rigid, well-anchored pole right next to the landing zone is worth padding — see our best pole pad guide.
