KIND REMINDER - HOW TO SET UP: Watching the set-up video on this Amazon image bar makes it easier to learn how to set the trap. Common Trouble Shooting Steps - Why is the trap door not working properly? -Due to the folding nature of this product, if the overall frame is not properly aligned during setup, it may affect the connection between the trigger rod and the pedal, thereby affecting the triggering of the trap door. - What should I do if the cage is loose? - Due to the folding structure of the product, after multiple folds, the buckle on the product will expand and cause the cage to loosen. You can use pliers to clamp these loose buckles, or you can use extra zip ties to secure the cage. (If the cage is too loose, it may also affect the triggering structure of the trap.) - If you have any other questions about how to use the product, please feel free to message us at any time.
