Our range of Knock Out Seals are manufactured from a Nylon 6/6 and are available in two flammability rating grades, these being UL94V-2 where vertical burn stops within 60 seconds and UL94V-0 where it stops within 10 seconds, without any flaming drips from the material. These products are designed to temporarily blank off an electrical plug or access hole, but allow for future access by easily knocking out of place when required. Each size of Knock Out Seal is carefully produced to a number of standard industry and trade hole diameters.

All Knock Out Seals finished in Silver are manufactured to the UL94V-2 standard, where-as the Black versions meet the UL94V-0 grading. Please note this information is also displayed within the measurements on the product detail page, however if you are unsure please give a member of our team a call.
