Why this kit

Full-circumference lip lids seal well and open badly. Keep the lip locked on the pail; open a cut panel instead. Pair with an intact shell for collection, or with the rack bucket shell for modular and municipal banks.

Build guide

Mark, cut, hinge, and tune steps—including safety—are on the full build guide (HTML; works offline in the PWA). Print that page or any schematic from the browser for paper.

  1. Seat the stock lid on an empty matched pail; note molded handles; mark the largest panel with ≥25 mm land (handle opposite hinge).
  2. Cut the sub-lid; deburr.
  3. Hinge on the rack bottom-of-face edge; confirm gravity-open when tilted.
  4. Use molded pull if present; else optional string or light latch.
