• The Mounting Channel Framework supporting the “ROPE GRIPPER™” must withstand
upward and downward forces according to Table 1 (p. 4) and applicable code requirements.
• The Mounting Channel Framework must be sufficiently sized to securely hold the “ROPE

prevented from sliding. See Figure 2 and Figure 3 (pp. 2 – 3) for suggested mountings.
