USE WITH HORIZONTAL SYSTEMS:
The SRDs covered in this instruction are compatible for use with horizontal
systems, such as Horizontal Lifeline (HLL) systems and horizontal rail systems. See the manufacturer instructions of your
horizontal system for more information on its compatibility with SRDs. SRDs may be used with a horizontal system only if
both products allow for such use.
;
Required Fall Clearance values presented in these instructions are based on use with a rigid, stationary
anchorage point. These values do not apply when the product is used with a Horizontal Lifeline (HLL) system. See the
manufacturer instructions of your HLL system for fall clearance charts specific to that system, or for additional factors
that must be accounted for before using the charts in these instructions.
