The Pet Prime 2 Ways Locking Pet Flap Door is a plastic flap door with a transparent panel and a four-position lock, listed at £35.89 in the Large size. It takes the number 9 spot in this guide, with a 4.5-out-of-5 rating from 492 reviews and a Best Sellers Rank of 7 in Doors for Dogs.

The size information is where this listing gets loose. The title says Large, the Dog Breed Size field says Large, and the Weight Capacity Maximum is 45 Pounds — roughly 20 kg. The £59.99 CEESC further up this guide claims up to 45 kg, so two doors can share the digits 45 and still be about two and a half times apart, purely because one figure is in pounds and the other in kilograms. The Pet Prime bullets do not close that gap: they say the range includes Small, Medium and Large sold separately, and give no flap measurements for any of them. The specification table also lists the materials as Metal, Plastic while the bullet text says only durable plastic.

Everything on this page is taken from the Amazon listing as published, not from any test of ours.
