QUALITY CONSTRUCTION

FOUR STANDARD COLOR-CODED SIZES

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 .

Our standard braces are offered in four basic sizes, with minimum
breaking strengths of 920, 1700, 4200 and 7000 lbs. Each is color-coded
in red, white, blue or yellow that insures proper designation on plans
and for installation in the field.

PRE-STRETCHED ASSEMBLY DAMPENS SEISMIC LOADS
QUALITY ASSURANCE & CERTIFIED BREAK STRENGTH

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.
™

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.
™

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.

THE SEISMIC BRACING SYSTEM
Our seismic bracing typically consists of the following components: the Seismic Wire Rope/Cable™, a factoryattached stake eye end treatment, an oval sleeve used to secure the cable loop, and a Universal Restraint Clip
(URC or 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 URC
clip. There are four sizes of oval sleeves, corresponding
to the four brace sizes. The hand swager tool is used
to swage the oval sleeves and is required to maintain
brace strengths.
