Sometimes, a Close-End Nylon Zipper may become misaligned, which can create additional challenges. If the zipper does not seem to close for reasons other than mechanical failure, check to see if it is functioning on the appropriate path. Misalignment typically occurs when stress is placed unevenly on the zipper through loading. To resolve this, gently pull the zipper to ensure it engages properly, ensuring that fabric is not preventing a smooth operation.
