Sitemate Ratchet Tie Down with Chassis Hooks for easy handling This ratchet tie down is 1" x 4m with a max load of 250kg. These straps are ideal for securing loads in trailers or vans or gathering items together and securing them. The end of the strap clips on to the side of the trailer and another strap feeds straight back into the ratchet handle to pull the load tight. Using ratchet straps is a much safer and quicker alternative to the old method of using ropes and knots. The ratchet straps can be tightened easily and then quickly released when needed.
