Discerning architects and builders insist that automatic gate mechanisms have to be invisible; this is especially important during the renovation of historical buildings. One of the best ways of maintaining the clean lines of a gate is to use QUIKO underground swing gate openers of the SUB range. These can be installed underground, safely out of sight, in their special foundation boxes with drainage holes to deal with rainwater. A handy feature is their easily accessible manual unlocking mechanism so that the gate can be opened manually during electrical blackouts. The gearmotors are lubricated with permanent grease and they are almost maintenance free. The optional accessory allows for a 180° opening of the leaf. All the components are tough and hard-wearing, made in steel, iron, aluminium and bronze using cutting edge technology and expert workmanship that guarantees reliability and long lastingness of the whole system.
