This product is ideal. I had to buy it because the Fuhr multipoint lock kit i bought from SDH ,although it was specified for a 44mm thick timber door, came with a strike plate that was far too small to reach the edge of the door frame! The one they state as 56mm is the one needed for this size door!! SDH were very helpful, quick with delivery and the Fuhr product was excellent quality, I am just seriously annoyed that i had to order and pay for this part that should have been supplied with the kit i bought. I spoke with SDH and made this point and they said they would investigate but i have heard nothing in 2 weeks and frankly don't expect to! Annoying when everything else was perfect and then to be let down by this situation.
