In ClimbTech BWA012N in rope access work where it is common for the D-ring to be rotated under body weight, the retaining nut may become loose over time. This possibility is accelerated when the swivel d-ring is not kept clean. It is recommended that examination of this component be added to before use, and periodic inspections of any affected product still in service. Depending on frequency of use, it may be necessary to carry out periodic inspections more often. It is also recommended that a straight permanent mark be made across the swaged region and the exposed flat face of the retaining nut to determine its current alignment.
