I am wondering whats the proper way of securing the frame in regards to the two thick metal support . For me , if I position the the two support right against the top and bottom inner part of the frame , it either presses against the grommets completely or is in the way of the strings . Shouldn't the support only be pressing against the frame itself ? For the time being , I have added load spreaders to counteract this problem . Please do let me know if I have misused the support in any way .
