FAB Rail System 2.0 – Tool-Free Assembly, Adjustable Height, Built for Breeders

Give your puppies the protection they need with the FAB Rail System 2.0—a safer, smarter pig rail setup that’s now easier to assemble and strong enough for large whelping boxes up to 7’ x 6’ in size.

Available Sizes & Outside Dimensions

Choose the size that fits your whelping box and space:
• 3’ x 3’ – Outside Dimensions: 34-1/4” x 34-1/4”
• 4’ x 4’ – Outside Dimensions: 46-1/8” x 46-1/8”
• 4’ x 6’ – Outside Dimensions: 70-1/8” x 46-5/16”
• 7’ x 6’ – Outside Dimensions: 81-1/16” x 70-1/8”
These measurements reflect the full assembled footprint of the pig rail system—critical for ensuring proper fit inside your whelping box.

Essential Safety for Your Litter

Also known as pig rails, these perimeter rails create a buffer zone along the inside walls of your whelping box. They help prevent accidental smothering by giving puppies a safe space to move if mom lays too close. Once your pups are bigger and more mobile, the rails can be removed to create more usable space.

Tool-Free Setup – No Hardware Required

No screws. No tools. No frustration. Rails and connectors fit securely into place for fast, hassle-free assembly—perfect for breeders who want a quick setup that’s just as easy to disassemble and clean.

Fully Adjustable Legs for a Custom Fit

Every rail includes adjustable-height legs, so you can easily modify the rail height depending on your breed’s size and the age of your puppies. Whether you’re raising a small litter or a larger breed, this system adjusts to fit your needs.

Stronger Support for Larger Boxes

To provide additional support across longer spans, T-supports are included in the larger size kits:
• 4’ x 6’ includes 2 T-supports
• 7’ x 6’ includes 4 T-supports
These mid-rail supports prevent sagging and keep the entire assembly stable—even with active litters and bigger boxes.

Safe Corner Design

Legs are designed to help prevent puppies from crawling into corners and getting stuck. It’s a simple feature with a big impact on safety.

Durable and Easy to Clean

Made from high-quality ABS and PVC plastic, the FAB Rail System 2.0 is built to last across multiple litters. Internal reinforcements reduce bowing, and the smooth, non-porous surface wipes clean in seconds—ideal for maintaining a sanitary whelping environment.

Each Kit Includes

• All rail sections
• Corner connectors
• Adjustable-height legs
• T-supports (included with 4’ x 6’ and 7’ x 6’ sizes)

Built for Breeder Convenience, Designed for Puppy Safety

The FAB Rail System 2.0 combines safety, flexibility, and ease of use—giving you a reliable, professional-grade setup that supports the health and comfort of your litter.
