Contractors use wire support systems because they are effective and easy to install. Although many different factors and features make some systems better for different applications, all wire rope support systems are comprised of the same basic components.


Wire rope systems may differ from one other based on the manufacturer. However, all wire rope support systems include:

1. Wire Rope

The wire rope is the cable with which the application is attached to the structural attachment. Different types of wire ropes are used for different load ratings. Common sizes include 1.5 mm, 2 mm and 3 mm. Because the cable is comprised of several strands of steel wire, it has a very high strength-to-weight ratio. As with all applications, product-specific materials should be consulted for the specific limitations of the system.

2. Locking Device

The locking device is the piece of hardware that holds the wire loop in place. Locking devices may look or install differently based on the manufacturer. Some locking devices are sold with small tools called “keys” that lock up or free the cable. Other locking devices may be keyless and simply require a manual manipulation to move the cable through it. Much like the cable, locking devices are limited to a specific load requirement. The load rating can be different than that of the cable, and installers should default to the lower of the two.

Inside the locking device, the wire is gripped with one or two spring-loaded cams that hold the wire in place. A single-cam device holds the wire by pressing it into the inside wall of the housing. A double-cam device holds the wire by clamping it between two spring-loaded cams. Double-cam devices generally have a stronger grip on the wire than single-cam devices.

3. End Fittings

End fittings are the hardware at the end of the wire rope made for a specific application. Some examples of end fittings include angle brackets, shot-fire pin brackets and hammer-on flange clips. When used in the correct setting, end fittings can install quickly and provide a secure attachment to almost any structure.
