The standard internal jambs inclusion is 2040mm high steel door frames.
The RegalFrame steel joinery jamb has a beautiful built in architrave that when painted looks like a timber frame. Its square edges and large returns also give the frame an ultra modern look when painted. The RegalFrame is made from a 1.1mm Galvanneal, which is the strongest frame in the domestic door frame market.
The best way to determine if a frame is a left or right hand opening is to stand and face the door so that it opens towards you. If the hinges are on the right hand side then the frame is a right hand opening frame. If the hinges are on the left the frame is a left hand opening frame.
