Grommets are used in conjunction with the LK810 form mounting kit. These grommets are used to secure the LENTON INTERLOK couplers in repeatable locations in the formwork. Once a coupler is placed over a grommet, the form mounting kit bolt is tightened, which expands the outside diameter of the grommet, thus holding the coupler on location.


  • Color coded for the appropriate coupler size
  • Durable and reusable
