A load attachment system such as commonly used as a horizontal lifeline safe ty system (10) includes a substantially horizontal lifeline (14) secured at its ends to a building structure (12) an d supported intermittently along its length by intermediate supports (26, 126). Each support (26, 126) includes a horizontal bar (38, 13 8) for supporting the line (14). The system (10) further includes a load attachment device (24, 124) having a pair of grooved rollers (54, 56; 154, 156) that rides on the lifeline. A load ( 18) is supported from the bottom (68, 168) of a C-shaped member (62, 162) which has its top (64, 164) connected to the rollers (54, 56; 154, 156) thereby allowing the device (24, 124) to traverse the supports (26 , 126). The bottom (68, 168) of the C-shaped member also carries a rotatable paddle wheel (74, 174) which prevents the device (2 4, 124) from being removed from the line (14). The paddle wheel (74, 174) rotates when a paddle (78, 178) is engaged by the support's horizontal bar (38, 138) as the device traverses the support (26, 126).
