When it comes to transporting temperature-sensitive cargo, stability is just as important as refrigeration. Whether you’re hauling food, beverages, floral arrangements, or medical supplies, even minor shifts during transit can cause serious problems. That’s where an E-Track system comes in.
Why Install E-Track?
E-Track offers a secure, customizable solution for cargo management. By installing this on your Polar King Mobile trailer, you gain:
- Improved Load Security: Prevent boxes, bins, or pallets from sliding or tipping during transit. This is especially important for delicate or perishable products.
- Increased Versatility: Attach straps, bars, or fittings at various points along the track to accommodate different types of cargo.
- Better Organization: Keep loads compartmentalized and stable, reducing damage and making unloading more efficient.
- Enhanced Safety: A stable load helps prevent accidents caused by shifting cargo when doors are opened.
Installing E-Track in Your Polar King Mobile Trailer
Our trailers are designed to make modifications like E-Track installation simple. There’s a layer of ¾” plywood underneath the fiberglass interior, located in the raised portion of the wall, this provides a strong and secure anchor point.

Installation Steps:
- Position the Track: Center the E-Track on the raised interior panel of the trailer wall.
- Secure with Screws: Use #12 x ¾” stainless steel pan head screws to fasten the track at each end and then at intervals along the length.
- Standard spacing: Every 5th hole.
- Optional for extra strength: Every other hole.
- Customize Your Setup: Once installed, the E-Track system can be adapted using a wide variety of accessories to suit your cargo needs.
Built for Flexibility
Installing E-Track is just one of the many ways Polar King Mobile trailers can be customized to better serve your business. Whether you’re delivering frozen goods to restaurants or managing supply routes for medical facilities, an E-Track system helps ensure every load arrives intact.
