• For installation of stainless steel systems, 3M recommends using a general purpose thread lubricant on all fasteners to
prevent abrasion. Apply it liberally. Threads should be lubricated on the entire length and all the way around the bolt
(Figure 23). The included thread lubricant should be applied as one tube per U-bolt.

WELDING RECOMMENDATIONS: Some installations require welding brackets to the structure. DBI-SALA recommends
that welding be completed by a certified professional welder in accordance with applicable national welding codes or
standards. Base and filler materials must be compatible with galvanized or stainless steel, depending on the materials of
your system. Protect finished welds from corrosion with coating or paint.
3.4
RUNG SUPPORT: Rung supports can be used to reinforce hollow rungs. This will prevent the crushing or collapsing
of the rungs when tightening of the Safety System Clamps, and to 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 22 for examples of rung supports.

REVERSE HARDWARE INSTALLATION: When desired, the connecting hardware of the top and bottom brackets can
be installed with the threaded portion facing away from the users. This is achieved by adding a backing plate to each
U-Bolt to capture the ladder rung:
- 6100753 Galvanized Steel Backing Plate (Figure 13)
- 6100745 Stainless Steel Backing Plate (Figure 13)

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.
