2.7.3 Minimum Required Fall Clearance for up to Two Workers w/SRDs
When attaching up to two Self-Retracting Devices (SRD) to the FallTech SteelGrip® Cable HLL system shown in Figure 5, it is permissible to
calculate the required clearance below the working surface by including the typical SRD deceleration distances detailed in the SRD user's
instruction manual. Calculating total clearance requirements using typical performance attributes for the SRD will generally
result in reduced clearance requirements.
