030-0550 Heavy Duty Pivoting Catch Compartment Latch

Designed For:

  • On or off-highway vehicle applications--construction, mining, agricultural
  • Service and utility truck body doors
  • Most storage, compartment and access doors
  • Electrical switch and transformer boxes


  • The high strength steellaminated hook resists wear and increases strength
  • Heavy duty zinc diecast paddle resists deformation
  • Retrofits the same cutout as the 030-0500 Pivoting Catch Compartment Latch
  • Pivoting catch allows relative movement between the door and frame when the vehicle frame flexes
  • Components are spring loaded internally to minimize effects of vibration
  • Reverse paddle design of the compartment latch is suited for top hinged doors and provides resistance to insertion of foreign objects
  • Two levels of performance/duty: the heavy duty version (030-0500) provides a higher level of resistance to vibration and wear


  • All steel reinforced construction


  • Zinc plate, yellow chromate conversion coat for maximum paing adhesion and resistance to ruse
  • Black powder coated


  • Key locking - keyed alike with most common key codes to match paddle actuators used for operator enclosures
  • Non-locking
  • Padlocking for increased security
  • Optional hole patterns


  • Lock cylinder may be installed after the latch has been assembled into the door and painted
  • Four 3/16" diameter steel "pop" rivets or 1/4-20 screws (not included)
  • CAUTION: Compartment latch does not meet FMVSS 206 load requirements.
