SafeTack: The Safest Horse Trailer Patented Design - A Double D Trailers Exclusive

Born from a Real Injury. Refined by Decades of Innovation.

In 1999, a horse owner reached through the side slats of her trailer to clip a halter lead. With one toss of the horse’s head, her arm was broken.

That incident, combined with years of watching horse owners struggle with cramped trailer layouts, led Double D Trailers founder Brad Heath to design something entirely new.

“We saw people putting themselves at risk. Getting pinned walking in with their horse. Reaching through slats. Trying to lead horses into a dark, narrow box. It wasn’t safe. I knew we could fix it.”
—Brad Heath, Founder, Double D Trailers

The result was a rear-load trailer called the Tack-Around™. In 2011, that concept evolved into what’s now the SafeTack® Reverse Slant Load Horse Trailer, which earned U.S. Patent #9132762.

The Behavior Behind the Design

Around the same time, a customer shared a study from the Journal of Veterinary Behavior with Brad. It showed that horses travel with less stress when facing backward.

“She told me she couldn’t find a trailer that was rear-facing and safe to use. So we started from scratch and built a new layout that gave her both.”
— Brad Heath

What’s Wrong With Traditional Designs?

Most reverse slant trailers still suffer from the same old problems:

• Fixed rear tack compartments that block the rear exit
• Narrow 36–39" ramps that make horses feel trapped
• Tight interior layouts that force horses to back out or twist
• One-sided access with no clear escape route for the handler
• Limited airflow from poorly placed windows or vents
  

In these designs, handlers walk in beside the horse, putting themselves at risk of being pinned or kicked, or they lead the horse in loose and reach in through slats to secure it. That’s a dangerous way to load.

SafeTack® Reverse Solves All of It

This patented layout was engineered to solve every one of those safety concerns for both horses and handlers.

 Key Features:

• Swing-Out SafeTack® Compartment: Fully clears the rear opening so horses can walk through a wide, open exit.
• Double-Hinged Dividers: Dividers swing both ways, so horses can walk forward to unload, no awkward backing required.
• Side Load, Rear Unload (or vice versa): You choose the direction. Load from a large side ramp, unload from the rear, or flip it.
• Drop-Down Windows + Pop-Up Vents: Provide airflow and visibility regardless of direction.
• Rear Safety Partition: Prevents premature unloading when the ramp is dropped.
• Ramp Placement Options: Install the ramp on the curb or driver’s side, giving flexibility in emergencies.

“We always build in two escape points for the handler and clear access to each horse in case of emergency. That’s non-negotiable.”
— Brad Heath

What Owners Are Saying

“You swing out the tack compartment, latch it, and it’s like loading them onto a stock trailer. This is the trailer you need.”
— Cindy, PA (2 Horse Bumper Pull)

“We love the extra space, the rear or side loading options, and being able to unload away from traffic if we ever break down.”
— BJ & Allison, TX (3 Horse Gooseneck)

“Our horse would get nervous with traditional rear tack trailers. The SafeTack® layout makes everything easier.”
— Pam, TN (1 Horse LQ)
