Track: 8′ Premium Track

The safety and functionality of your sliding stall doors begin with how securely your track is mounted to the wall. Our 1/4″ x 4″ Hex Head Lag Screws are the exact heavy-duty fasteners required to securely install an 8′ Premium Track System. A sliding barn door is incredibly heavy, and the mounting hardware must withstand the constant stress, vibration, and impact of daily barn chores. Standard screws simply cannot handle the load. These lag screws provide the deep, structural anchoring necessary to keep your track permanently fixed to your door posts.

Because equine facilities expose hardware to constant dust, humidity, and temperature fluctuations, these screws are fully zinc-plated. This protective coating delivers long-lasting rust and corrosion resistance, ensuring your track system remains structurally sound year after year. The hex head design allows you to drive the screw in with maximum torque using a socket wrench or impact driver without stripping the head.

Installation Note: Before fully setting your Premium Track, ensure the mounting holes align perfectly with your solid wood door posts. To install, simply fasten two 1/4″ x 4″ hex head lag screws—paired with two 1/4″ flat washers—through the holes along the top edge of the track directly into the door post locations.

  • Easy Hex Drive: High-torque hex head allows for fast, slip-free installation using a socket or impact driver.
