EVEN STRONGER MAGNETS THAN THE APALUS CLASSIC – The 18 extra-long magnets integrated into the magnetic strips are twice as strong as those in the classic Apalus magnetic fly screen door. This ensures the magnets hold the fly screen door securely closed, even in strong winds, and make closing the screen even easier. THE VP MATERIAL IS TWICE LONGER DURABLE than standard polyester fabric and withstands changing weather conditions and direct sunlight for longer. The sides of the fly screen are double-stitched, tear-resistant, and made of durable and robust VP material. Ideal for cats. The transparent insect screen is breathable, allowing you to enjoy summer even from the sofa. EXTRA 3.8 CM WIDE VELCRO STRIP – The widening of the Velcro strip from 2 cm to 3.8 cm at the top of the insect screen door ensures an even more secure hold for the VP fly screen. You can cut the extra-wide 3.8 cm hook-and-loop fastener for the top of the VP fly screen to your desired width. A fly screen door reliably protects you from unwanted guests. Includes a size selection and easy installation on front doors, side doors, French doors, sliding doors, patio doors, and basement doors.
