Offset links are commonly used for adding additional links into a chain. They are also commonly known as half links. These offset links are constructed entirely out of 304-grade stainless steel. Doing this has created offset links that can operate in harsh climates, corrosion resistant, and durable. This offset link is part of the General Duty Plus Series, which basically means that it will last longer and is more durable than offset links from the Economy Plus Series.
