Straps
Some states, including California require straps that have the rating marked on the strap along with the rating agency- In California it would be the CHP.
In South Carloina, certain containers and machines require chains at the trailer corners but straps are OK on the sides.
Most enforcement agencies consider torn or cut straps to be useless. There is a handy hard plastic 90 degree strap protector sold at most truck stops and places like New Haven Equipment ( they make pro-straps to order ).
Most home movers can put you in touch with a local strap source.
Small trailers and unbranded straps can cause functional and legal issues.
There is an agency called the " national association of trailer makers." I know Eager Beaver, Fontaine, Cozad, Trail King, Trail Eze, and others are members.
These manufacturers are agreed upon what it takes for a trailer to carry a certain weight rating and have engineering to prove it. These are the safest manufacturers to buy from.
Straps are easy but not as durable.
It is a good idea to contact the motor vehicle enforcement division in your state for securement specifications on your truck, trailer, and load.
Most states have info helplines available.
All loads over 10,000 require 4 point securement.
