Product Description

Split bolt connectors are electrical connectors used to connect two or more wires. They are called “split bolts” because they consist of a bolt with a split in the middle, which allows the connector to be opened for wire insertion. Then, tighten the bolt to secure the wires in place. These connectors are typically used in applications requiring safe, reliable connections between multiple wires. They are often used as an alternative to other types of connectors, such as crimp connectors, as they are considered more robust and reliable. They are also easy to install, making them a popular choice for electrical professionals.

Split bolt connectors are commonly used in grounding applications, such as lightning protection systems and electrical equipment. In these grounding systems, the connectors are used to join ground wires and other components, forming a complete circuit that provides a path for current to flow to the ground. Using these connectors in grounding applications achieves safe, reliable connections that can withstand the high currents and voltages associated with electrical grounding and lightning protection. To use split bolt connectors in grounding applications, installers first need to strip the insulation from the ends of the wires. Then insert the wires into the split of the bolt, ensuring they are positioned correctly. Use a wrench or other tool to tighten the bolt, clamping the connector firmly onto the wires to create a secure connection. Once all connections are complete, the grounding system can be tested and activated. In addition to grounding applications, split bolt connectors (also known as open bolt connectors) can be used for other parts of the system, such as wiring in protected buildings and structures. These connectors are suitable for a wide range of applications where safe, reliable connections between wires are required. Split bolt connectors are also ideal for fence grounding. In fence applications, they can be used to connect ground wires to the fence itself, or to join the fence to other grounding components, such as ground rods or surge protectors.
