<p>The reflector has a body of plate with a reflective surface on each side and a hole which goes through it. There is also a hook (18) which engages in the hole and also a hook (4) around a spoke (S). Both have fixings to secure them. The hooked part incorporates a nut, solid with it and a screw (5) which works with the nut. The hook and screw are at opposite sides of the screw. The screw has a head which presses against a side of the plate when in use. The spoke goes along the other side of the plate and rests partly in a groove in the plate.</p> |
