1 × 19, Type 316
stainless steel Cable.
1 × 19 construction Cable is engineered to hold static loads without stretching and it is relatively stiff. Left hand lay cable for use with all Ultra-tec® Fittings.
Our recommended cable for most applications is 1x19 construction, type 316 stainless steel cable.
Other constructions of cable can be used, such as 7x7 or 7x19, but they are rarely recommended.
| Cable Construction Type 316 Stainless Steel is used, unless otherwise specified. |
- To minimize deflection, cable needs to be:
- As rigid as possible and
- Resistant to stretch under load. Cable stretch is undesirable, and the longer the cable runs between terminals the more it will stretch as it is tensioned.

| Cable Construction |
Characteristics |
|
1 x 19
|
|
Very rigid. Lowest stretching under load. 1 x 19 is the preferred construction for cable railings, under most circumstances. |
|
7 x 7
|
|
Less rigid than 1 x 19.
|
May have application where sharp bends are involved and on shorter runs where stretch is a negligible factor. (Not readily available in left hand lay.) |
|
7 x 19
|
|
Less rigid than 7 x 7

Cable Applications

Typical Applications
|
|
1/8"*
|
Can be used on horizontal railings where there is little or no pedestrian traffic or where railing does not need to meet code requirements (such as where there is little or no drop off). Can be used on vertical railings, which are not as susceptible to heavy shock loads as horizontal railings. |
|
3/16"
|
Most commonly used diameter for pedestrian railings. |
|
¼"
|
Diameters larger than 3/16" can be used where a larger diameter is desirable from a visual/aesthetics standpoint. |
|
5/16"
|
|
3/8"
|
|
|
*1/8" diameter cable can be vulnerable to failure under shock loads caused by abuse, such as a heavy person applying an out of plane load on a properly tensioned cable. 3/16" and larger cable diameters have significantly higher load ratings than 1/8" and are, therefore, not as susceptible to failure as 1/8".

| NOTE: Ultra-tec® hardware is designed for use in pedestrian guardrailings. For other applications, consult the factory for suitability. |
Design Parameters and Constraints:
Cable has a very high tensile strength
and is a suitable in-fill material for a guardrail. Spacing between posts and/or braces should not exceed 42". Recommended maximum vertical spacing of 3" free opening between cables when they are installed. For most applications, 3/16" diameter Cable is recommended.
Other Cable constructions can be used, such as 7 × 7 or 7 × 19, but they are rarely recommended because of their elevated levels of stretch and lower breaking strengths in comparison to 1 × 19 construction. |
|
Measuring Cable:
The factory can cut Cable and swage fittings on Cables up to 60 feet in length.
To measure Cable when ordering pre-cut and swaged Cable:
- Clearly identify fittings – by part number – that are to be used with the Cable.
- For Invisiware® Receiver, Radius Ferrule or Clip-On Stop hardware, measure from back side of the post.
- For Adjust-A-Jaw®, Adjust-A-Body™, Threaded Stud with Welded Receiver or Fixed Jaw hardware, measure from the inside surface of the post .
- For Adjust-A-Jaw®, Adjust-A-Body™ or Fixed Jaw hardware, you may also measure from the center of the mounting hole.
- Measure rail as if all are straight from tensioning post to anchor post. If rail is on a slope, measure on the slope.
|
Note: Re-spooling charges apply for orders under 5,000 feet.
