Logistic ratchet and cam buckle straps, motorcycle tie-downs, rope tie-offs, D rings, and other accessories with spring fittings can all be inserted into these E-Track slots with a press of a lever, making reliable load securement easy.Galvanized Steel E-Track Vertical RailThis vertical E-Track rail is made of 12 gauge heavy-duty steel, with a galvanized finish that delivers increased corrosion- and rust- resistance. It is available in 4, 5 and 10 foot lengths.Cargo can be secured with the different E-Track accessories that we carry, such as our E-Track fittings and rings.Galvanized E-Track Installation In Your Enclosed TrailerSymmetrically aligned holes on these rails make this trailer E-Track easy to install on your flatbed or interior van trailer by using 1/4" screws, bolts, or rivets. Be sure to align the e-tracks parallel to each other if more than one are utilized, this will guarantee that each end fitting is fitted into the same slot of each track. Ideally, every 3rd, 4th or 5th hole on each side of the E-Track should be anchored tightly to your trailer. After loading your goods into your trailer, slip each end fitting into the slots of the E-Track, and you should hear a 'click'.
