Surprise frame for glass door
This frame features doors with a special sliding system that allows one door to slide telescopically into the other, which in turn slides back into the metal box in the wall. The particular design of the Surprise frame means it can only be used with Lorica doors from the Unique range.
Available in single and double versions, for masonry walls only.
Also available in non-standard sizes, in heights varying to the nearest centimetre.
