Anchor & Bow Shackles

Round pin anchor bow shackles are used to connect lifting, towing, or tie-down equipment where a larger loop is needed inside the shackle body. These shackles have a rounded shape that provides more space for attaching gear. The round pin is held in place using a cotter pin, making it easy to set up and take apart when needed.

At Holloway Houston, we carry round pin anchor bow shackles in sizes from 1/4" to 2". Each size comes with a matching working load limit, ranging from 0.5 tons up to 35 tons. These shackles are often used in situations where gear moves slightly or where space is needed to attach multiple pieces of rigging. The round body helps reduce pressure on connected parts by spreading the load across a larger area.

This style of shackle is often chosen for pulling, light rigging, and support jobs where the load stays steady. Since the round pin is not threaded, it’s easy to remove and reinsert with fewer tools. Once the cotter pin is set, the connection stays in place until you’re ready to open it again.

Holloway Houston works with well-known makers such as Green Pin to provide anchor shackles with smooth surfaces and proper alignment. The consistent sizing and clean threading help make gear changes easier in the field. These shackles are marked with size and working load for easier selection.

If your job needs a different pin type, Holloway Houston also offers screw pin anchor shackles. These have a threaded pin that can be removed by hand and are often used when setup changes are more frequent. Both round pin and screw pin anchor shackles are shaped the same, but the pin style is chosen based on how the shackle is used.

Round pin anchor shackles are often used for steady setups that don’t need to be checked often. The cotter pin helps keep the round pin from coming loose, which is helpful for long-term use in static connections. These shackles are often found in towing chains, lifting frames, load restraint kits, and support lines.

If you're looking for a straight-sided option, Holloway Houston also provides round pin chain D shackles. These are better for single connections where a compact shape is needed. Both options follow the same quality standards and come in sizes that match your setup.

Every product page lists the size and working load to help with quick comparison. Common sizes such as 3/4", 1", and 1-1/2" are used in everyday rigging jobs, while larger sizes like 1-3/4" and 2" are available for heavier jobs. These shackles are used in industries like marine, oilfield support, and equipment transport.

You can also find replacement cotter pins and accessories on the Holloway Houston website. Keeping spare pins helps reduce downtime if small parts are lost during fieldwork.

These shackles are clearly marked with load capacity and size, either by stamp or tag. While color may sometimes help identify size, we always recommend reading the markings to confirm load limits.

One benefit of the round pin style is that it does not need tools to install. Once inserted and locked with the cotter, the pin stays put during steady loads. This helps reduce the time needed to set up gear, especially when working on the ground or in tight spots.

Round pin anchor shackles are often picked for tie-down jobs or static connections that don't change often. They offer more space inside the bow than a D shackle, which makes them helpful when you’re attaching to wide straps, thick slings, or multiple links at once.

For gear that is used more frequently or moves more during the lift, bolt type anchor shackles are also available. These have a nut and cotter pin setup, offering extra hold when gear is under more strain.

Other related products at Holloway Houston include master links, lifting points, and chain slings, which can be used with round pin shackles to build a complete rigging setup. All items are listed by size and load rating to help with gear matching.

To keep your shackles in good shape, check them often for rust, pin wear, or damage to the bow. Clean off debris and add light oil to the pin if the shackles are being used in damp conditions. Make sure the cotter pin fits correctly to hold the round pin in place without gaps.

Round pin anchor shackles offer a simple way to join rigging parts where the load is steady and space is needed inside the shackle. Whether you're working with web slings, tow lines, or setting up anchor points, this style fits many support jobs. Holloway Houston stocks each size and keeps items ready for shipping to help you get the gear you need.
