WIRE & CABLE HANGERS
EARTHQUAKE SWAY BRACE SYSTEMS FOR CABLE TRAYS
Legrand has joined with Loos & Co., the industry's top manufacturer of Seismic Wire Rope/Cable™
QUALITY CONSTRUCTION
Our standard braces are constructed of a splayed assembly of either
49 or 133 high strength, zinc coated, steel wires, configured into
Wire Rope/Cable
™
.
PRE-STRETCHED ASSEMBLY DAMPENS SEISMIC LOADS
Our Seismic Wire Rope/Cable
™
is pre-stretched in accordance with
ASCE-19. This allows our cable to act in its elastic range; in essence, it
behaves like a shock absorber.
SPECIAL DESIGN & INSTALLATION FEATURES
Every brace is designed to resist earthquake loads in tension and they
are not restricted in length as are compression braces. Standard braces
are extremely flexible, lightweight and are offered in precut lengths,
with or without fixed end fastener fittings.
line of seismic protection products specifically designed for electrical cable tray applications. All our Seismic Wire Rope/Cable™
Bracing, to provide a comprehensive and unique
bracing, complies
with model building codes, and installs in just one-third the time needed for more conventional pipe, angle, and strut bracing systems. Our exclusive
systems have no length limitation and are UL listed.
THREE STANDARD COLOR-CODED SIZES
Our standard braces are offered in three basic sizes, with minimum
breaking strengths of 600, 1100 and 2800 lbs. Each is color-coded in
gold, orange and green that insures proper designation on plans and for
installation in the field.
QUALITY ASSURANCE & CERTIFIED BREAK STRENGTH
The manufacturer conducts a rigorous in-plant program of inspection,
testing, and retesting of all its Seismic Wire Rope/Cable
™
products to
meet code and industry standards. A Certificate of Minimum Breaking
Strength is included with each shipment.
THE SEISMIC BRACING SYSTEM
Our seismic bracing typically consists of the following components: the Seismic Wire
Rope/Cable™, an oval sleeve used to secure the cable loop, and a Universal Restraint
Clip (URCR) or a No Pry Clip (NPC). Hardware required to connect the cable tray to the
braced component and to the building structure are not included in the brace kits.

OVAL SLEEVE
The oval sleeve secures the cable loop through the
URCR clip. There are three sizes of oval sleeves,
corresponding to the three brace sizes. The hand
