UERS101 Non-magnetic Stainless Steel Constant Force Roll Spring

Constant Force Springs are a range of solderless connections for use on lead or aluminium sheaths and copper screened cables. The springs are easily applied by rolling onto the sheath connections, whereupon it continues to exert a constant pressure,even under load conditions.
Using constant force springs is an easy and reliable way to earth the cable joint and termination systems as they constantly exert pressure on the earth braid to achieve a reliable continuity.
 

Features

 The spring is resilient, non-magnetic.
 The spring is corrosion resistant,Anti-oxidant.
 The spring provides a constant and lasting force to the connection
 The spring is manufactured from stainless steel EN standard 1.4310
 The spring can be applied by hand without any tools
