The 4 PK (YAZ292N) 1-3/4 Hole Spacing Compression Lugs are designed for secure electrical connections with a focus on durability and ease of use. These lugs feature an inspection window that allows you to verify that the wire has been properly inserted and crimped. To use, strip the insulation off the end of the wire, insert it into the compression lug until it reaches the bottom, and then use a crimping tool to compress the lug securely onto the wire. The electro-tin plating provides corrosion resistance, making these lugs suitable for various applications. Finally, check the inspection window to confirm that the wire is fully visible and properly secured for a reliable connection.
