A module for use with an expandable wedge clamp assembly in a chassis channel is provided. The module comprises a first side, a second side, a first extension attached to the first side, and a second extension attached to the second side. The first extension and the second extension are flexible. When the wedge clamp assembly is expanded, the first extension and the second extension flex from a first position to a second position. When the wedge clamp is returned from the expanded position to a relaxed position, the first extension and the second extension return from the second position to the first position.
