Tiedown rings are used to secure cargo during transportation. Fastening a rope, cord, cable, or chain to the ring anchors the item in place, preventing movement and potential damage. Flush-mounted tiedown rings function as surface mount anchor points that include a d ring (or tiedown clevis) that folds inside the base.

The S33000ML series tiedown conforms to Mil Std 209K.

This style incorporates a fully weldable housing that can be flush mounted rather than surface mounted like its sister tiedown, the S33000E series. It rotates 360 degrees about the vertical plane and 150 degrees horizontally. It will swivel and swing to the load plane within these angles. The d ring/tiedown clevis works with hooks or you can lash flat bands to the ring's crossbar. For greater capacity, check out our 10,000 LB. capacity flush swivel tiedown or our 50,000 LB. capacity flush swivel tiedown.

We stock self-colored bulk-backed kits; however, a variety of corrosion-resistant finishes are available, including galvanizing followed by a black Dacrokote finish to reduce the reflectivity of the galvanizing (this finish was selected for the medium tactical vehicle replenishment program). The tiedown can be shipped as an assembly if preferred.
