hi can any one help ive a small tear in the zip vent the fly net comes off to replace i dont know how it caught on the middle cover bracket but has thanks

Do you mean a tear in the mesh vent or to actual pop top fabric?

The tear could have been caused by pulling down the pop top without the door open thus causing the compressed air to push out the canvas to become caught in the scissor bracket. Is this what you mean? You can replace the mesh relatively easily but how you repair the canvas I bow to somebody more knowledgable.
