Inspect all cargo on the trailer to ensure there is nothing on the trailer that cannot be tied down. Place small items in a wood crate to be able to tie the crate down to secure the items. Push all cargo in toward the center line of the trailer and butt together all cargo so no shifting occurs in transit.
Hook the hook end of the strap or chain to the side rail of the trailer and throw the excess strap or chain over the cargo every 5 feet of cargo length. If a piece of cargo is shorter than 5 feet and does not have cargo in front of it then two straps or chains should be used to tie down the cargo.
Tuck all straps into the thin slotted openings of the steel wenches on the side rail of the trailer and hand tighten. Place strap protectors under the straps where any cargo that could cause the strap to be frayed or cut are found. Slide the tip of the cargo securement pry bar into the hole of the wench and begin tightening the strap until the cargo is securely tied down.
Pull the excess chain links to the unhooked side of the trailer and hook the hook of the chain to the side rail. Hook a steel chain binder on the length of the chain coming from the already hooked side and then to the length coming from the side you're standing at. Use the open end of the cargo securement pry bard on the handle of the chain binder and tighten down the chain until the cargo is securely fastened to the trailer.
