Tie-Back Connection Example
Figure 3 Illustrates typical Latitude HD Tie-Back SRL-P anchorages and connections. Safewaze Latitude HD Tie-Back SRL-Ps can be connected to an anchor
point from 11” to 21” in diameter. Select an anchorage location with minimal free fall and swing fall hazards. Select a rigid anchorage point capable of sustaining
static loads as defined in Section 6. Depending on the Tie-Back circumference, Latitude HD SRL-Ps can be used below D-ring per OSHA requirements. See
diagrams below for examples.

FIGURE 3 - TIE-BACK SRL OPERATION
Specific models of the Latitude HD SRL-P series are designed and tested for use below the Dorsal D-ring. The user must account for additional clearance
requirements when the anchor point is located below the D-ring. Safewaze Latitude HD SRL-Ps meet all ANSI Z359.14-2021 requirements for a
Class 1 SRL when anchored overhead. When anchored below the Dorsal D-ring, Latitude HD SRL-Ps are compliant with OSHA 1910.140 and OSHA 1910.66.
Table 9 indicates the Minimum Required Fall Clearance (MRFC) for each type of SRL in the Latitude HD line. Table 9 also provides the Maximum Allowed Distance
below the D-ring a Latitude HD SRL-P may be used, as well as the Actual Arrest Distance as tested for each unit. Both are factored into the MRFC calculation.
NOTE:
Minimum Required Fall Clearances indicated in Table 9 DO NOT account for potential Swing Fall hazards. If Swing Fall
hazards exist, they must be factored into any MRFC calculation.
