***** **********Best Quality Guranteed. *****2 complete sets of D-rings and backing plates. Both components are zinc coated to inhibit rust and corrosion. The d-rings have square holes punched for receiving carriage bolts, providing a smooth and relatively trip free surface. When in use the ring portion raises for application and lies down when not in use, thus creating a flush surface. It is plenty strong and is able to receive multiple tie-down straps simultaneously. *****Each D-ring has a 6, 000 lb straight pull capacity.
RATED CAPACITY: Also known as "assembly capacity" or "break strength" is the minimum load a complete assembly can withstand before failure in a laboratory pull test when the product is NEW.
WORKING LOAD LIMIT: The maximum load weight a tie-down should be subjected to during normal use. To assist in making the proper tie-down choice the Federal D. O. T. requires the W. L. L. to be 1/3 of the Rated Capacity.
*****SPECIFICATIONS of d-ring: 1) The base measures 5" x 4-1/2".
