The corner connector is attached by means of countersunk screws DIN 7991 M8x25 and very easy to assemble. Thanks to the high-quality distribution of metal, this makes it very easy to assemble frames or hoods. The matching cover cap made of solid plastic is orderable optionelly. This provides additional protection after installation thanks to its flattened edges. Guide lugs may need to be broken off for profiles with covered slots. An M8 thread is also required for installation..
