Multi Function Connecting System EFA
EFA Multi Function Connecting System, - all mounting points exist twice and are self-locking. 1 even tolerate small inaccuracies because l'm adjustable on both sides. This applies to my right, left, upper and lower side as well as for lay-on or lay-in constructions. There are also additional fixed points that allow you to easily secure the screwing position. My screws of choice are 04 or 4.5mm countersunk-head screws.
