4-Pack - Recessed Pan D-Ring Trailer Tie Downs (6,000 Lb. Capacity) and Heavy Backer Plates, Including Mounting Hardware (Complete Set: 16 Carriage Bolts, Washers and Nylon Lock Nuts)

• 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". 2) Hole pattern is 3" x 3-1/2" on centers. Recessed dimension is 3" diameter with a flat edge. 3) The 7/16" diameter ring measures 1-3/4 center. 4) The ring pivots on a 5/16" threaded stud. 5) The pan has a 1/4" drainage hole. HARDWARE: This listing comes with two (2) hardware kits, enough to finish the installation. Each kit comes with 4 - 3/8" x 2-1/2" long carriage bolts, 4 - fender washers, and 4 - 3/8" superior NYLON LOCKING NUTS.
• BACKING PLATE is used for support under the floor when installing the tiedown attachments, and prevents the bolts from pulling through. SPECIFICATIONS: 1) The backing plate measures 6-1/2" x 6-1/2". 2) Thickness is 11 gauge (a little thinner than 1/8). 3/8" holes. 3) 3-1/2" diameter cutout. 4) Steel backing plate is zinc coated to inhibit corrosion.
• INSTALLATION - these D-rings require routing, or cutting a hole in the floor. We recommend creating/cutting a template and then transferring to the desired location. If you use a 3-1/2" hole saw, the d-ring will fit without any further work. Better fit - use a 2-3/4" hole saw then jigsaw the flat edge and then bevel the entire edge with a wood hasp to create a snug fit.
• International products have separate terms, are sold from abroad and may differ from local products, including fit, age ratings, and language of product, labeling or instructions.

Hardware Kits: This listing comes with 4 hardware kits, enough to complete the installation. Each kit comes with 4 - 3/8" x 2-1/2" long carriage bolts, 4 - fender washers, and 4 - 3/8" nylon locking nuts. The 2.5" bolts are long enough to go through 2" thick planks which is typical on an open trailer. IMPORTANT - Most enclosed trailers have 3/4" thick floors. The 2.5" long bolts will work on 3/4" floors but are longer than what is needed. Therefore if you prefer 1-1/2" bolts please message us and we'll be happy to provide the shorter bolts. APPLIES to seller fulfilled orders only. This tie down attachment has a 6,000 lb. capacity* vertical pull weight rating. To install this attachment requires routing, or cutting a hole in the floor. This recessed d-ring has square holes punched for receiving carriage bolts, providing a smooth and relatively "trip *" surface. The steel attachment is zinc coated to inhibit corrosion. When in use the ring portion raises for application and lies down when not in use, thus creating a flush surface. This tie down attachment is plenty strong and is able to receive multiple tie-down straps simultaneously. To obtain maximum strength it is recommended to install these d-rings with bolts, lock nuts, and fender washers. For installation purposes it is easiest to cut a template and then transfer to the desired location. * 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.
