This two-part grommet is specifically designed for HDS single Ethernet installations that incorporate LSS and N2k. Instructions: 1 - Drill a 3mm pilot hole exactly where you want the grommet to be located. 2 - Drill a 9mm hole 13.5mm to the left of the pilot hole, as clearly indicated by the accompanying diagram. 3 - Use a hole saw to drill a 25mm hole right through the center of the pilot hole. 4 - Carefully guide all cables through the central hole in the following order: first, LSS; then, transducer (sonar); next, Ethernet; followed closely by power/data cable, paying attention not to include the plug end; and finally, N2k. 5 - Secure each cable into its designated slot within both halves of the grommet. 6 - Place both halves together, ensuring they are perfectly aligned with the 'key' provided for easy assembly, then gently insert them into the main hole.
