Here at Loos Seismic Bracing we recieve some questions frequently from potential and current customers. Below you can look at some of the questions we commonly recieve and our answers, written by our Seismic Bracing Cable experts! 


We strongly recommend using our Engineers’ Tools. Using this calculator guides the user step by step to create and save designs for multiple projects. You can also calculate your total cost of materials for your project and then will have enough information to begin your seismic bracing project. 

Unlike rigid bracing, you do not need to have different size pipes to complete seismic bracing installations. With cable you will be able to just cut your spool of cable to the desired length you need, making the process fast and allowing you to quickly move to your next seismic bracing job site installation. The small size of our product also makes transport easy and fast. 

Rather than providing a step-by-step guide here, we recommened you our expertly written design guides. If you require a more visual installation how-to guide, check out our available installation videos here. Additionally, our Engineers’ Tools make it easier than ever to fill out the NFPA-13 Seismic Bracing Calculation form and caluculate your material costs for the project. 

Our bracing cable is available in four sizes, #GO3-CBL Gold Cable, #OR4-CBL Orange Cable, #GR6-CBL Green Cable, and #BL8-CBL Black Cable. Each cable has a different load rating and comes in 250 ft. spools.

There is no maximum size! As our cable comes in 250 ft. spools, when you need to secure a large object you can just use a long length of cable from the spool.

Cable & Hardware

No! One of the best things about seismic bracing cable is that the diameter of your cable is one size, meaning you will only need to use one fitting type. In rigid bracing projects, all the different size pipes have different diameters which means you would need to have multiple sizes and types of fittings to complete a bracing project. 

Our attachment hardware is zinc-plated to provide superior resistance to corrosion and other elements.


Along with our bracing cable, we also offer attachement hardware, bracing kits, swaging & crimping tools, and cable cutters. You can learn more about each of these products by going to our main product page here.

Loos offers the complete line of Swiss-made FELCO® Brand Cable Cutters. The two we offer through our Seismic Bracing website are the C7 and C9 models. However, if you want to check out the full line of FELCO® products we have available, go to our Cableware Division website here

When you want a powerful swaging tool that has repleacable dies, allowing you to swage plated oval sleeves for #GO3 (GOLD), #OR4 (ORANGE), #GR6 (GREEN), and #BL8 (BLACK) sizes, our SL-7NDK-SB Battery Swager is the perfect tool. Hand swagers are cost effective but limited to only being able to swage one specific size, depending on the tool.

Cable Bracing Benefits

While there are many reasons to consider switching from rigid to cable sway, if we had to pick three it would be the cost difference, ease of installation, and efficency. Rigid bracing has long been considered the seismic bracing standard, however its flaws in requiring numerous types of fittings for installations, various pipe sizes being required, and heaviness make the solution much more cumbersome than cable bracing. 

As the bracing is fairly light and easily portable, you can technically complete installations with just one crew member. Rigid commonly requires at least three people to work on bracing installations, so seismic bracing is much more convenient. 

Seismic cable is considered to be a much cheaper alternative than rigid. Seismic cable takes up much less room in inventory and does not need to be transported on long bed vehicles to fit various pipe sizes. The installation also requires less time on the job and fewer crew members. These factors plus the inherent cheaper cost of the product make seismic bracing far cheaper than the tools required for rigid bracing. 

The switch is one to one! You will find the transition over to cable sway bracing seamless and after learning how to properly install the bracing by reading our design guides or watching our how to videos you will be completing seismic installations in no time!
