The corner connector is attached by means of pan-head screws M8 x 30. Thanks to the high-quality distribution of metal, this makes it very easy to assemble frames or hoods. The matching cover cap round made of solid plastic is included in this set and can be attached directly after the connection. This provides additional protection after assembly thanks to its flattened edges. Guide lugs may have to be broken off for profiles with covered slots. For mounting, an additional M8 thread is required..
