R&P Service Insight
A tie down anchor is only as strong as the anchor, the mounting hardware, and the surface it is mounted to. Always install into a structurally sound location and keep the load within the rated working load limit.
- Mounting Surface: Confirm the trailer floor, wall, truck bed, or utility body panel is strong enough for the intended load.
- Load Rating: Rated at 800 lb working load limit with a 2,400 lb break strength.
- Install Check: Verify mounting hardware and backing support before tying down cargo.

What This Means: This listing is for one Buyers Products B21 tie down anchor. It is not a lifting ring, recovery point, or hoist-rated component.

R&P Repair Insight
Replace cargo tie down anchors when they are bent, cracked, loose, heavily corroded, or mounted into damaged material. The rating of the anchor does not override a weak floor, wall, rail, or fastener setup.
- Check the Ring: Do not reuse if the ring is stretched, bent, cracked, or visibly worn.
- Check the Clip: Inspect the one-hole mounting clip for distortion or corrosion around the bolt area.
- Check the Mount: Use proper support or backing where needed so the anchor does not pull through the mounting surface.
