- Sits Inside of a Top Rail Sleeve
- Allows Top Rail to Expand and Contract Without Bowing or Becoming Disconnected
- Use with Galvanized or Coated Chain Link Top Rail Sleeves
Chain link sleeve expansion springs fit inside of the sleeve and provide greater freedom of motion to the rail, which is important because top rail will contract in extreme cold and expand in extreme heat. If your top rail expands during the summer, it could bow and weaken. Likewise, if you cut the rail short to account for the expansion, the could become disconnected from the sleeve when it contracts in the winter. The spring will help ensure this doesn't happen.
