FIBERLIGN^® Cushion Clamp

The FIBERLIGN Cushion Clamp uses a combination of structural reinforcing rods (SRR) and elastomer inserts at the ends of the clamp halves to protect the OPGW from damage at support points.

Reduces negative effects of wind-induced cable motion, such as aeolian vibration, galloping, and sway
Can accommodate either left-hand lay or right-hand lay OPGW
A galvanized 1/2"-13 x 3/4" UNC bolt and lock washer are provided with one of the clamp halves to attach a ground wire assembly with a terminal lug to it for bonding OPGW to the supporting structure or a ground lead
Each clamp half has two factory-installed elastomer cushion inserts to minimize stress at clamp ends
Clamp halves have a machined central groove that ensures a proper fit and provides electrical continuity
Clamp halves are secured with two captured 1/2"-13 galvanized steel U-bolts
Clamp halves and SRR are high-strength aluminum alloy. Fastening hardware is galvanized steel.
An optional ground wire assembly can be included with the cushion clamp
SRR cannot be reused after they have been installed. Hardware components can be reused as desired if they are in good condition.
The FIBERLIGN Cushion Clamp has been thoroughly tested for vibration, mechanical loading, and optical attenuation in accordance with IEEE Standard 1138 and IEEE Standard 1591.1
