MOst of those CHEAP all in ONE pretty looking Chinese IMPORTED doors are Rubbish! They are made from Paper thin metal sheeting which have been CUT open by regular kitchen Can openers and broken into. The All in One 4 point locksets that come in them are problematic and terrible and when it DOES go bad they cannot be serviced or changed . The ENTIRE door must be changed ot cut and retrofitted.
CASFAB limited in elsocorro manufactures Strong Fire rated Steel doors and frames, they service if EVER necessary and they manufacture to FULL international Standards.
