The locking mechanism shown on the box is the correct one for my frig rm257abrs/xaa. The locking mechanism on the actual filter is different and does not fit. Idiots at Samsung will tell you the the filter mechanism has changed which is incorrect and sell you on a service call. You can buy other brands cheaper that have the right lock. Unbelievable you think by getting a brand buy the manufacture it would be correct.
