Universal Grounding Clamps

MacLean Power design philosophy is to maximize the utility of our grounding clamps.  All MacLean Power ground clamps, including all universal clamps, were designed specifically to withstand asymmetric faults.  Each clamp is manufactured to the latest ASTM F855 standard and has been tested at independent laboratories per ASTM F855. 

Universal design elements allow the clamp to be used on conductor, round bus bar, grounding studs and grounding ball studs.  One clamp can cover multiple customer needs. 

Universal Design Benefits

Our universal safety clamp covers multiple applications eliminating the need to purchase and maintain an assortment of clamps.


The Universal Clamps can be used on:
  • Conductor 
  • Round Bus Bar
  • Ground Studs and Ground Bar Studs
