3.2 Ladder Modification (Optional)
Warning: When using tools to cut or drill metal, use eye protection and follow all other safety precautions recommended by the
tool manufacturer and required by applicable safety regulations. Use caution and wear safety gloves when handling metal parts
that have been cut to length. Sharp edges can cause personal injury and property damage.
Note:
Do not modify the SRCABLELADDER18 accessory unless you have followed the instructions in
Section 3.1 Planning
and determined that modification
is required. If modification is not required, proceed to
Section 3.3 Ladder Assembly
.
1
Measure and mark the cable ladder section that will be cut.
2
Use a hacksaw or other metal-cutting tool to cut through the ladder section. Make sure your cut is perpendicular to the length of the
ladder and use a metal-cutting tool that will not bend or crush the ladder section.
3
(Optional) After cutting, use a drill with a 3/8-inch bit to drill new pin holes in end of the ladder section. Compare the modified end of
the ladder section with the unmodified end to determine where holes should be drilled. Make sure that the hole location matches your
planning and measurements. You may omit this step, but drilling the pin holes and installing the pins will make the SRCABLELADDER18
accessory more stable.
