"The screw holes are parallel to the shank and the knob protrudes beyond the centreline making it impossible to access the screws with a screw driver. If put in at an angle, the heads protrude because the countersink is at the wrong angle and force the fitting to move. Really disappointing, because they look good."
"Ordered 16 of these. The shanks barely go into the knobs at all, leaving you with enough shank for a 3" thick door. Life's too short to cut them all down with a hacksaw! Returning the lot. The chrome finished equivalent parts don't have the same problem - shanks slide fully into the knobs."
