Bigg Frame

CannonBall began in 1916 by Hunt, Helm and Ferris Company in Harvard, Illinois. In today's post frame and metal building markets, there are lots of choices available for building accessories and components. Choosing the right components for your project will play a critical role in feeling satisfaction.

  • The Bigg Frame System is ideal for large doors over 144 square feet – offering a standardized construction, fewer components and easy assembly.
  • Designed for buildings with roll-formed siding, Bigg Frame Systems remove the guesswork and labor associated with field-fabricated doors.
  • The versatile Bigg Frame design allows for adaption into a wide assortment of special applications including bypass, split-slider and multi-panel doors.
  • All components of the Bigg Frame System come with a powder coat finish for a durable, quality appearance that will outlast paint under all weather conditions.
  • NOTE: This system is NOT recommended for wood horizontals.

#391 Bigg-Frame Vertical Side Rails

Designed specifically for larger door panels, Bigg Frame’s 391 Side Rails offer self-flashing J-channels to enclose steel door skins for a trouble-free hold and easy installation.

  • Sturdy, rust-free aluminum materials offer long-lasting functionality, finished looks and quick assembly.
  • Side rail profile conceals all exposed steel, giving the panel a smooth, clean edge that won’t cut or scratch.
  • An optional vinyl weather seal can easily slide into the built-in T-slot for quick, easy weather sealing.

#396 Bigg-Frame Double Couple

Larger sliding doors demand strong connections to keep out the elements – and the Bigg Frame 392 Double Couple handles the job with greater stability than standard H-rails.

  • The Double Couple is designed to replace one side rail — aligning both sliding door panels together when the door is closed.
  • H-rail functionality wraps the edge of the joining door panel for a sturdy connection, increased unit durability and added sliding door system longevity.
  • A built-in J-channel offers easy installation of the door panel skin.

#394 Bigg-Frame Bottom Rail

Designed to accommodate a continuous guide rail, the 394 Bottom Rail delivers increased wind resistance and diminished sliding door sway during use.

  • When used in conjunction with a continuous guide rail, the 394 Bottom Rail offers ease of use and protection of building siding.
  • Two built-in channels within the rail allow for the use of an optional vinyl or brush seal to keep out dust, dirt, rain and snow.

Steel Girts

Designed for ideal horizontal support on sliding door frames, the 235 Steel Girt is a 20-gauge galvanized steel beam sized for optimal door frame construction and support.

  • Long lasting, rust-free materials avoid the rotting and warping issues associated with 2×4 lumber.
  • The hollow girt design offers more strength and less weight than comparable lumber horizontals, providing easier installation and lighter full-assembled doors.
