The tightener 1030C may have a knurled periphery and/or one or more slots for a screwdriver or other tool. As the tightener 1030C is rotated about the end portion 1020 of the positioning member 1008A it advances the contoured jaw 1022A along the positioning member 1008B.

As shown in FIG. 3D, attachment assembly 1060D may have a positioning member 1008A, a contoured jaw 1022A, a washer 1062, a pivot 1080, a cam lever tightener 1030D, and a retainer 1082. The pivot 1080 may have outwardly directed posts 1088 and an internally threaded portion that cooperates with an externally threaded portion in the end portion 1020 of the positioning member 1008A. The tightener 1030D may have a cammed surface 1084 and openings 1086 sized to accept posts 1088. As the tightener 1030D is rotated about the posts 1088 of the pivot 1080, the cammed surface 1084 advances the contoured jaw 1022A along the positioning member 1008A. The retainer 1082 may have an anti-rotation post 1094 that cooperates with a slot 1092 in the end portion 1020 in the positioning member 1008A to prevent the tightener from rotating about the axis of the end portion 1020. The retainer 1082 may have one or more openings 1090 sized to accept posts 1088. As shown in FIG. 3E, attachment assembly 1060E may have a positioning member 1008A, a contoured jaw 1022A, one or more washers 1062, a pivot 1090, a cam lever tightener 1030E, and a retainer 1092. The pivot 1090 may have outwardly directed posts 1094 and a through-hole 1096 sized to slide over an externally threaded portion in the end portion 1020 of the positioning member 1008A. The tightener 1030E may have tabs 1104 having cammed surfaces 1102 and openings 1106 sized to accept posts 1094. As the tightener 1030E is rotated about the posts .1094 of the pivot 1090, the cammed surface 1102 advances the contoured jaw 1022A along the positioning member 1008A. The retainer 1092 may be internally threaded to cooperate with the externally threaded portion in the end portion 1020 of the positioning member 1008A and may include a locking feature to resist removal. The retainer 1092 may be rotated about the externally threaded end portion to provide fine adjustment of the distance between the contoured jaw 1022A and the first structural member 1014 on the mounting plate 1004A. The tightener 1030E may have an elongated opening 1106 to allow the tabs 1104 to be spaced apart while the tightener 1030E is coupled to the posts 1094 of the pivot 1090. A fastener 1108 may be used to urge the tabs 1104 back together. The elongated opening 1106 may have a portion 1114 sized to allow an end portion 1116 of a spring latch retainer 1110 to extend therethrough. The spring latch retainer 1110 may be used to prevent unintentional rotation of the tightener 1030E. The end portion 1116 of the spring latch retainer 1110 may be aligned with the portion 1114 when rotation of the tightener 1030E is desired. The spring latch retainer 1110 may be secured to the mounting plate 1004A, 1004B with a suitable fastener 1112.
