To develop full cable loop working
strength, cable clamp nuts must be
torqued to at least: 65 ft-lb on 1/2-in. clamp
nuts. 95 ft-lb on 5/8-in. clamp nuts.
To ensure proper torque, apply torque in
stages to both nuts alternately.
Use a staggered nailing pattern when
lumber or laminated lumber is nailed to
the floor of a railcar. Adjust the nail
pattern so that a nail going through a
piece of lumber on the top of the stack is
not driven into or against a nail in a
lower piece of lumber.
