Built to handle the heaviest sliding door panels, Double Truck Trolleys are the perfect choice for steel frame doors on Heavy Duty Track with Universal Bracketry. Round Track End Caps are included with these trolleys (no hardware).

Features:

• Model variations include Delrin wheel or steel wheel models
• The product design features four wheels per trolley, allowing it to support door weights up to 1200 pounds per Delrin-wheeled pair (900 pounds per steel-wheeled variety) -- when used in conjunction with Heavy Duty Track and brackets spaced every 12" on center.
• An optional plate sits just below the top girt, preventing the bolt hole from distorting.
• Double Truck Trolleys have a variety of bolt styles and length options to provide extra flexibility in mounting
