D.
INSTALLATION OF W1 SYSTEM:
See Figure 7 for a typical installation of the W1 System on a wooden pole. The top bracket should be positioned to
allow users safe access when connecting or disconnecting from the system. Use 1/2-inch fasteners (not provided)
to attach the top bracket to the pole. Fasteners should extend through the pole when possible. 3M DBI-SALA
recommends using lock washers, double nuts, or other methods to ensure fasteners will not loosen.
E.
INSTALLATION OF CE1 SYSTEM:
See Figure 8 for a typical installation of the CE1 System. The top bracket should be positioned to allow users safe
access when connecting or disconnecting from the system.
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.
F.
INSTALLATION OF T1 SYSTEM:
See Figure 9 for a typical installation of the T1 System. The top bracket should be positioned to allow users safe
access when connecting or disconnecting from the system. Typical applications include access ladders into manholes
or under trap doors. Do not substitute other fasteners.
Installation procedure:
1.
Top Bracket: Install clamp plates and fasteners as shown. Torque fasteners as specified.
2.
Bottom Bracket: Install fasteners as shown. Torque fasteners as specified.

INSTALLATION OF CARRIER CABLE ASSEMBLY TO TOP BRACKET:
A.
INSTALLATION OF CARRIER CABLE ASSEMBLY:
1.
Lay the carrier cable assembly out on the ground in a clean area by rolling the coil. Do not pull cable from center
of coil. For some installations it may be easier to lower the carrier cable from the top connection level down to the
bottom bracket. If so, carefully lower the cable by unspooling without twisting the cable at the top connection. Do
not drop the cable to the lower level.
; Carrier cable is very stiff and may spring out of coil unexpectedly. Use proper safety procedures when unrolling
cable. Use appropriate safety gear, including gloves and safety glasses, when unrolling cable.
Inspect the cable for shipping damage before proceeding. Do not install damaged cable.
2.
See Figure 11 for installation of the carrier cable into the top bracket. Ensure the end of cable is free of kinks and
unraveled strands.
Installation procedure: Insert lug end (C) of carrier cable assembly into the side of the top plate (B) profile at an
approximate angle of 45 degrees while pressing against spring gate (D). The small pin (E) and spring gate (D) are
designed to prevent the lug/cable assembly from inadvertently disconnecting from the top plate (B). Make certain
that only the large pin (A) rests inside the top plate (B).
3.6
INSTALLATION OF CABLE GUIDES, ALL MODELS:
Cable guides protect the carrier cable from chafing against the structure and to prevent the climber from excessively
deflecting the cable from side to side. Cable guides should be positioned at approximately 20-40 ft (6-12m) along the
carrier cable between the top and bottom brackets, and at any point along the system where the cable may abrade
against the structure. Cable guides should be staggered along the system to reduce harmonic effects of the wind, such as
at 23 (7.01), 25 (7.61), and 27 (8.23) feet (m) intervals. For high wind areas, "L" shaped cable guides may be used. The
"L" shaped cable guides should be alternated with openings on the left, then right, etc., up the structure. Latching cable
guides are also available.
Direct Connection to Structure:
See Figure 12 for a typical installation of a cable guide. Some cable guides utilize rung spacers and clamp plates while
others do not (see Figure 12). Install the cable guide using the hardware provided. Do not substitute other fasteners.
Torque fasteners to 20-25 ft-lbs (27-34 N-m).
3.7
TENSIONING THE SYSTEM:
; Depending on the length of the system, and the environment in which the system is installed, it may be
necessary to periodically re-tension the system. Extreme temperature ranges and very long systems will likely
require periodic re-tensioning.
Carrier Cable Tension Adjustment:
1.
See Figure 10. Thread tensioning nut (A) onto end of tension rod (B) so that 3-5 threads are exposed below the nut.
Insert cable into saddle clamps (C). Lift up on tensioner assembly until tensioning nut bottoms out on bottom washer
(D). Tighten saddle clamp nuts and torque to 35 ft-lbs (47.5 N-m). Tighten tensioning nut until groove (E) is exposed
above top bracket. Tighten jam nut (F) against tensioning nut. Cut off excess cable just below the lower saddle clip.
4.0 IDENTIFICATION AND INSPECTION AFTER SYSTEM INSTALLATION:
A.
Install the installation and service label onto the structure in a prominent location. Use the steel wire provided with
the label to attach it to the structure. Before installing the label, mark the following:
•
Installation Date
•
Installed By
•
Maximum Users Per System
•
System Length
Use a metal letter stamp to mark the label. Record the system identification information in the Installation Checklist
at the end of this manual.
