Description

PDF

Opening and closing tool for standard (ribbed) lids of canisters (1L-60L) used in schools, laboratories etc. This is an alternative to the conventional wrench style designs commonly used for this application. I found this design to offer plenty enough of leverage to get the canisters open, thanks also to it's ergonomic shape.

  There are currently two sizes available for the respective standardized threads:

  • DIN 51

  • DIN 61
