The Ferplast Swing 11 Medium Dog Flap with Wind Stopper sits at number seven in this guide. It is a brown flap with a magnetic lock, a stated opening of 21.8 x 25.5 cm, and a four-way lock that can be set to entry only, exit only, free entry and exit, or fully locked. The listing prices it at £39.99 and it carries 4.4 out of 5 from 3,250 ratings, with a category rank of 23rd in Doors for Dogs.

The figure worth checking here is not the size word but the price gap inside the same model. The Swing 11 flap is listed at £48.07 in white and £39.99 in brown, so the colour alone accounts for £8.08. The size language is looser: the title says Medium, the bullet talks about medium-sized dogs and large cats, and the only opening given is 21.8 x 25.5 cm — roughly the size of a sheet of A5 paper — so measure your pet rather than trusting the word. Everything on this page comes from the Amazon listing as it stands, not from any test of ours.

## Questions people ask

**What size pet will the Ferplast Swing 11 fit?**

The listing quotes a 21.8 x 25.5 cm opening and describes it as room for medium-sized dogs and large cats, with the spec table giving the dog breed size as Medium. Those are the only size figures the advert provides.

**How thick a door can the Ferplast Swing 11 be fitted to?**

The spec table lists a maximum compatible thickness of 38.4 Centimeters, while the bullet says the included sliding tunnel supports thicker installations. The overall size is also given as 31 x 9.6 x 38.4 cm, so the thickness figure repeats the 38.4 cm dimension — worth checking against your own door before buying.

**Does the Ferplast Swing 11 stop draughts?**

The listing says the Wind Stopper reduces incoming air to support a more comfortable indoor space. It does not quote a measured draught reduction.

**What locking options does it have?**

Four, according to the listing: entry only, exit only, free entry and exit, or fully locked. The closure type is given as a flap with magnetic lock.

**Where can the Ferplast Swing 11 be installed?**

The listing says it is designed for wood, metal and glass doors or brick walls when correctly prepared, and that the included sliding tunnel supports thicker installations.

**Why does the brown Ferplast Swing 11 cost less than the white one?**

The listing does not explain it. It is the same Swing 11 flap priced at £48.07 in white and £39.99 in brown, a difference of £8.08 for the colour.
