This CNC cut set of grommet plates is ideal for those engines with a need to pass connectors across the firewall (eg Rotax 912is/915iS and ULPower engines). Produced to provide a single point transit for connectors that can pass through a standard 80mm instrument punch hole in the firewall, the grommet plate makes provision for most if not all electrical wires to cross the divide. Produced out of 0.9mm 304 stainless steel there are two 20mm grommet holes and one 22mm grommet hole, with 3 grommets provided in the kit along with eight AN4 rivets to secure the plate to the firewall. We recommend that you use a suitable hi temp paste (such as Dirko/Elring or a Loctite) around the grommets and also between the plates/firewall. Some deburring may be required,
