TL;DR Canadian-made third-party insert with Venturi-style radial grid and rubber locking tabs for 3·8 gallon round buckets. Named-bucket community citations not on file. Well-reviewed by a large owner base on Amazon.
The Dirt Lock is a premium resin bucket insert from Canadian brand Detail Guardz, sitting 2.75 inches above the bucket floor with a Venturi-style radial grid. Rubber locking tabs self-adjust across a claimed 3·8 gallon range. Community reception is strong, highly rated by a large owner base; no re-suspension or structural complaints visible.
Right pick for a standard round 3·5 gallon bucket user who wants a Venturi-grid insert with a heavier-than-average build and rubber locking mechanism. Skip if you use an oval or non-round bucket · the round-bucket fit won't seat flush.
Passive insert · no chemical exposure pathway; health score reflects physical-use only. Mixed-material construction limits recyclability; no take-back program for this category.
