PG Clamps

Parallel Groove Clamps (PG)


  • Extended lip aligns clamp as bolt is tightened. Clamp base section forms a weather shield for the grooves. Compound stays in place, connections last longer.
  • Bolts are made of high-strength aluminum alloy and maintain high contact pressure during heating and cooling cycles.
  • Rotational tightening method for 396.6, 395.5 and 490.0 clamps provides accurate torquing. Set assembly finger tight and wrench tighten bolt indicator 1-1/4 turns.
  • Extruded clamps can be applied “hot” without taking them apart. No losing nuts or washers or fumbling for loose parts.
