- 4 complete sets of D-rings, backing plates and 2 1/2" hardware kits. Installation instructions included. 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". 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.
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 free" 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.
