Part #:   MB Gripper Load Bars

  Heavy-Duty Load Bars by     

  • 220-Pound Load Capacity on most vehicles for carrying most any load type!
  • Easily attaches to most factory-installed (OEM) and aftermarket "raised-side-rail" style Roof Racks and Roof Rails.

IMPORTANT NOTE: Adding these Load Bars to factory-installed Roof Racks or Roof Rails does not increase the vehicle manufacturer's load capacity for said roof racks or rails.  Please consult your Vehicle Owner's Manual for the specific Load Rating / Capacity.

  • If your vehicle does not have an OEM raised-side-rail Roof Rack or Roof Rails, installing our Aventura or DynaSport products in conjunction with our MB Gripper Load Bars provides a 220-pound load carrying capability.


  • Rectangular bars available in 47", 62", or 74" crossbar lengths, galvanized steel with black vinyl cover.  
  • AeroWing Bars available in 47" lengths, Satin anodized aluminum extrusion with black vinyl insert in top of crossbar.
  • Theft-Proof, Locking clamp assemblies adjust for variable spacing between roof rails, as well as:
  • Full front-to-rear adjustability allows for spacing between crossbars to accommodate various load types (dependent upon rail type and configuration)!
  • Rubber-padded clamps protect roof rails from damage.
