O&MM Fabricator - March/April 2017 - 27

Include load bearing in cable railing post
selection and follow the manufacturer's recommendation as to the cable tensioning sequence.
Your supplier will also recommend minimum
dimensions for your post. A good supplier can
also provide pre-drilled and counterbored posts
and pre-swaged cable assemblies to simplify
the installation process.
Confirming Structural Ability: Post size is
not enough to confirm the structural ability of
your cable railing installation. For example, a
two-inch, schedule 80 steel pipe post would
certainly have the ability to withstand a structural load. However, if you surface mount that
post to a wood deck with a cover flange and
some screws, it poses potential structural
risks and highlights the importance of embedded attachments. Cable railing uniquely
adds tension that impacts structural ability.
To confirm structural ability and prevent any
costly, time-consuming rework, take the time
to attach or embed the post in a manner that
will provide a structurally stable environment
for the complete system and the later introduction of the cables.
Adhering to Proper Tension Requirements:
How often have you seen cable railings as you
wander about where the cables droop between
posts? Unfortunately, it's not uncommon. Cable
and fittings do not all perform equally against
various conditions.
It's important to understand the incredible
amount of tension that can be generated with
multiple lines (i.e. ten or more). Consider, that
each is often tensioned at 225 lbs. - which
is why recognizing the amount of the tension applied to the posts is critical. Cable
that stretches easily under tension will sag
over time resulting in unhappy clients and
code inspectors.
If your cable railing is considered to be a
guard, you will also need to make sure that no
opening is large enough to allow the passage
of a four-inch sphere. For horizontal guards,
in-fill cables not properly spaced and tensioned will fail this 4-inch sphere rule - and for
the installer that is a liability. Consider spacing your cables at 3 to 3.25 inches on center;
tension properly; and include posts or cable
supports every 48 inches. Additionally, don't
make assumptions about stainless steel cable.
It's available in different strand diameters and
configurations - many of which allow for too
much stretch.
Not only is it a liability, but the tensioning
process can cause considerable bending as
the cables are being tensioned or even when

properly tensioned without an acceptable
amount of post deflection. The posts to which
hardware is mounted must be constructed so
that they will not deflect perceptively as the
cables are tensioned.
Cable railing hardware choice will depend on
your post selection and the amount of field labor
you are able to provide. Parts can be provided
pre-swaged from the manufacturer or tools may
be purchased or rented to permit final assembly
at the job site. Swageless fittings are now readily available to further simplify the installation
of cable railings.

Don't Let Challenges Get
in the Way of Opportunity
While your particular application is unique to
you, it's likely that your supplier has the experience and knowledge to provide you with the
best solution. Your supplier, as a resource, can
guide in selecting and working with the right
material, and serve as a resource for questions
to match each job for a given installation. As
the design world continues to leverage cable
railing for open and clean views, you don't have
to let the challenges stop you from getting the
most out of cable railing systems.
