      When designing a belt for your sidewall conveying needs, a key component of the design is the “pocket size”. The pocket size is the area between the inside of the sidewalls and the cleat.

      There are several rules-of-thumb used to determine the correct pocket size for your application:

      • Cleat pocket must be 2 times the size of the largest particle being conveyed

      • The cleat height should be 75% of the maximum particle size if the angle of incline is less than 75 degrees

      • If the angle of incline is greater than 75 degrees, the cleat height should be 150%, or 1.5 times, the maximum particle size


      When determining pocket size, cleat style should also be considered. Apache’s Durowall Sidewall Belting offers the following cleat styles for your application:

      T-Cleat

      • Vertical cleat 
      • Used to convey material up to a 35 degree incline angle
      • Cleaner removal of material at the discharge end


      C-Cleat

      • Scoop style angled cleat 
      • Used for inclines over 35 degrees
      • Greater carrying capacity than T-cleats


      S-Cleat

      • Vertical for the first 60% of their height, then bend at a 40 degree angle for the rest of the height
      • Form a bucket when used in a vertical application
      • Used in applications where the incline is over 45 degrees
      • Designed for steep inclines and high tonnage applications
      • Vertical portion of cleat allows it to be mechanically attached to the sidewalls creating a more stable and durable conveying pocket

      Our Durowall sidewall belting offers a wide variety of cleat compounds in both single and 2-piece construction. Many of our larger cleats contain a double layer of fabric reinforcement for added strength. Our rubber compound has a higher durometer than corrugated sidewall and belt cover, in order to allow cleats to maintain its shape and integrity when transporting heavy material in steep-angle applications.
