In today’s environment of new Seismic Bracing Codes and retroactive enforcement policies, the term RETROFIT might be on a lot of minds these days. What are your options when the code requires that past jobs be retrofitted to be compliant with current codes? In all too many instances the existing installations of HVAC and other mechanical systems, plumbing systems, and electrical cable trays, leave very little room for the installation of new seismic bracing components for Fire Sprinkler applications. Attachment of the braces to the building structure is critical, as is spacing requirements and the horizontal load factors of the bracing components. All of these factors combined can make new code compliance difficult and very expensive; especially if re-installation of entire fire sprinkler systems is necessary.
The fully Code-Compliant Seismic Bracing Cable by Loos
& Co., Inc. offers a solution to this dilemma. Loos & Co, Inc. is headquartered in Naples, FL and has been active in the Fire Suppression Industry for over 20 years. You may have seen Loos exhibiting at key industry trade shows such as AFSA, NFSA, and NFPA. Loos supports all of these associations.
Loos offers a complete line of Seismic Bracing products that are manufactured from galvanized aircraft cable and they are color-coded for easy field identification of the different sizes and load strengths. The cables operate in tension only, and two cables are required at each brace location to secure the Fire Sprinkler piping or the braced component.
The cables install easily, requiring only hand tensioning. Loos offers the versatility and the information needed to install cable braces anywhere from 30 to 90 degrees to the braced component measured from vertical. Permanent end fittings called zinc-plated oval sleeves are hand-crimped using Loos’ crimping tools (battery-powered tools are also available). The permanent end fittings do not damage the cables and they hold and exceed the breaking strengths of the cable when installed according to Loos’ easy-to-follow instructions which are included with every installation tool.
