If the ladder rungs impede the connection of two guide rail
sections, the rail sections can be bolted together using the
alternative holes on the rail connector (see Fig. 3c). In this
case, the guide rail must be fixed on the long side of the
rail connector at a maximum of 22 in. (560mm) away from
the joint (where the rung clamp is installed on the ladder
rung - see Fig. 3d).
Follow these steps to install additional guide rail while
proceeding up the ladder. Follow section 5.4 when
installation of the final guide rail section is required.

5.4 Installation of Top Guide Rail Section
The top guide rail section may be installed to end with the
top of the ladder or it may extend a maximum of 36 in.
(914mm) above the top ladder rung to provide for safe entry
onto a platform. In either case, the top rail section of the
system must be a complete 10 ft.-1 in. (3.08m) section and
must be secured as specified below.
If the top guide rail is to end with the top of the ladder [a
maximum of 12 in. (305mm) above the top ladder rung], one
rung clamp is required on the top ladder rung (see Fig. 4a).
Follow procedures for installing rung clamp.
If the top guide rail section is to extend above the ladder
[a maximum of 36 in. (914mm) above the top ladder rung]
, three rung clamps must be installed--one on each of the
top three ladder rungs (see Fig. 4b). Follow procedures for
installing rung clamps.
ansI note: With the top guide rail
section extending above the top of the
ladder, a guide rail reinforcement bar
must be used to meet ansI a14.3-08
standards. Call Honeywell technical
service at 800-873-5242 for information
on available reinforcement bars and
their use.
