I ordered the door guard for our cats. For larger dogs safely unstable. Delivery arrived very quickly, the contents of the package was complete - all chic. The actual grille is approximately 75cm wide. Who needs grow wider need extensions. It took me 2 Extensions A 20 cm. Delivered once were 20cm and 2 times 10 cm. In principle, no matter, but because the extensions only be inserted into the main grid stability of the whole is suffering enormously. The door closes on its own by means of spring mechanism and brings in slamming the whole powerful to wiggle. Furthermore, the door width of 55 cm is very narrow. With a shoulder bag on the body you will ever hang. In itself, the basic mesh is strongly built - if the extensions would perhaps screwed there 5 Star.
