Swiveling Weld-On Tie-Down Rings


Style A	Style B

Before welding, these rings swivel all the way around to accommodate ties in any direction. Weld them to any surface for a more secure connection than other tie-down rings.

Warning: Never use for lifting applications.

Style B—Style B rings are angled, making it easier to attach bulky ties and straps. They also protect ties and straps from abrasion to prevent them from wearing down over time.

Accommodate ties in any direction with these rings that swivel all the way around.

Warning: Never use for lifting applications.

Style B—Style B has a loose ring that twists to minimize abrasion on webbing and rope.

Concrete Fall-Arrest Anchors

Clip your fall-arrest lanyard to a secure connection point on approved concrete surfaces. These anchors expand into a hole, locking against the sides to form a secure hold. They swivel 360° as you move. When used together with a harness and lanyard, these anchors help you meet ANSI and OSHA safety standards.

Wedge In

Wedge-in anchors are more secure than push-in anchors. They expand in the hole as you turn the bolt.

Push In

Push-in anchors are easier to install than wedge anchors, and they’re reusable. Expand and release them by pushing a button. You can attach them to vertical or horizontal surfaces. Made of stainless steel, they resist the weather and grime that could decrease an anchor’s lifespan.

Fall-Arrest Anchors

Connect fall-arrest lanyards to these anchor points. You'll want to install these into an approved, stable surface that is strong enough to support someone. When used together with a lanyard and a harness, they help you meet OSHA and ANSI safety standards.

Swiveling Extension Spring Stud Anchors

A black-oxide finish provides these steel anchors with mild corrosion resistance. The head swivels 360° so the spring stays straight and properly coiled. Attach an extension spring to an anchor and then thread the anchor into your part for a secure connection. To make tightening easier, anchors have a hex socket on the bottom and wrench flats at the top of the threads.

Bolt-Style Sleeve Anchors for Block and Brick

Remove the bolt so the anchor is flush with your walls and floors to slide components past these anchors, making it easier to install or make adjustments. They’re best for door frames that need to be pressed into place or machinery you service frequently. All have a sleeve that expands inside your hole to create a strong grip. Since the gripping force is distributed along the entire length of the anchor, it won’t crack soft materials like block and brick. You can use these anchors as an alternative to wedge anchors in concrete near edges, corners, or other weak points, but they are not as strong.

To install, drive the anchor through your component into a drilled hole until the head meets the surface. Then, tighten the bolt to expand the anchor sleeve. As you tighten, the nylon ring compresses to secure the component against the surface. You can remove the bolt, but the anchor itself cannot be removed.

Anchors with Hex Head

Corrosion-Resistant 18-8 Stainless Steel—The choice for wet and outdoor environments, these anchors resist rust. However, they’ll corrode or pit when exposed to salt water and chemicals.
