I have a pair of (almost) 8' long load locks at their shortest length. $35.00. for both of them.
They haven't been used but maybe 5 times at most. I will be moving and don't want to lug them around with me. Located in Vacaville, California. If you need a pair of these and are coming through the area, I could bring them to you if/when you stop (but let me know ahead of time so I can borrow a pickup).
These photos show them inside a small 8' long trailer.
