TRIS is the shelf support slotted into the shelf by making edge borings.
The sleeve of the shelf support can be expanded by inserting a pin (pin=optional extra), which improves the structural fastening of the shelf to the sides of the furniture.
The shelf has to be pushed downwards onto the side brackets, which can be screwed into any position required.
The side brackets slot into the socket of the shelf supports and a click locks the shelf in position.
The TRIS brackets are available in 3 different versions: with spreading bush and screw pre-inserted, and with hole for screw fixing, with pin Ø 5 only for 25 mm shelf thickness version.
TRIS is available for 19, 25, 28 and 30 mm shelf thickness.
