3.3 RUNG SUPPORT: Rung supports can be used to reinforce hollow rungs to reduce crushing or collapsing of the rung due
to tightening of the Safety System Clamps, and to generally strengthen the rung. The Rung Support must have sufficient
length extending on either side of the Side Rails to install Rung Support fasteners. Install rung support at each LAD-SAF
component connection point. The structure must be evaluated by a qualified person to determine if the load requirements
for the system are met.
Rung Supports are available in various shapes and lengths. For best results, select a Rung Support size that will fit closely
with the inside dimensions of the rung. See Figure 19 for examples of rung supports.

3.4 TOP BRACKET INSTALLATION: Before installing the top bracket it is recommended that the climbing structure be
evaluated by a qualified person to determine if the load requirements for the system are satisfied. The top bracket should
be positioned to allow users safe access when connecting or disconnecting from the system. The top bracket is typically
mounted in the center of the climbing surface for ease of climbing, but may be located towards the side if required.
A. INSTALLATION OF L1 AND L2 SYSTEMS:
See Figure 2 for a typical installation of the L1 and L2 Systems. The top bracket should be positioned to allow users
safe access when connecting or disconnecting from the system. Do not substitute other fasteners.
Installation procedure:
1. Top Bracket: Slide rung clamps (B) over tube and install fasteners as shown. Torque fasteners as specified.
2. Bottom Bracket: Install fasteners as shown. Torque fasteners as specified.
B. INSTALLATION OF L3 SYSTEM:
See Figure 3 for a typical installation of the L3 System. The top bracket should be positioned to allow users safe
access when connecting or disconnecting from the system. Do not substitute other fasteners.
Installation procedure:
1. Top Bracket: Slide rung clamps (B) over tube and install fasteners as shown. Torque fasteners as specified.
2. Bottom Bracket: Install fasteners as shown. Torque fasteners as specified.
C. INSTALLATION OF M1 AND M2 SYSTEMS:
See Figure 4 for a typical installation of the M1 and M2 System onto a monopole. The top bracket should be
positioned to allow users safe access when connecting or disconnecting from the system. The top brackets are to be
connected to the structure with a 3M DBI-SALA standoff or customer supplied stand-off support. Stand-off supports
must support the loads specified in section 2.2, and must be compatible with the LAD-SAF
Angle Leg and Round Leg Stand-off Installation:
See Figure 5 for the installation of the angle (A) and round leg (B) stand-off supports. Install stand-off supports using
the hardware provided. Do not substitute other fasteners. Torque 3/8-inch fasteners to 20-25 ft-lbs (27-34 N-m).
Install the top bracket to the stand-off support using the 1/2-inch fasteners provided. Torque 1/2-inch fasteners to
40-45 ft-lbs (54-61 N-m).
Weld-on Stand-off Installation:
Install the stand-off support (C) as shown in Figure 5. See section 3.2 for welding recommendations. The stand-off
must be perpendicular to the pole surface and in-line with the carrier cable.
; Installations that use the angle leg or round leg stand-off support brackets are limited to one user on the system at a time.
M1 and M2 System Installation:
See Figure 4. Installation procedure:
1. Top Bracket: Install top plate (A), hardware (B) and Single Point Anchor assembly (C) as shown in Figure 4.
Slide the D-Ring (D) over the assembly (C) before installing. Torque fasteners as specified.
2. Bottom Bracket: Install bolt, spacers and fasteners as shown. Torque fasteners as specified.
