  • Universal Locking Mechanism (ULM) secures the cover without a nut and accepts 5/16"–3/8" bolts (minimum 1-1/2" length); can also be bolted down using the speed nut shelf.
  • Structural reinforcing ribs and a reinforced rim increase load resistance for pedestrian traffic and routine lawncare equipment.
