Chain & 'D' Shackles

Round pin chain D shackles from Holloway Houston are used to connect lifting or pulling equipment. These shackles come with a straight-sided body and a round pin that stays in place using a cotter pin. This type of pin allows for quick setup and removal. They are mainly used in applications that don’t have strong side loads or constant movement, such as towing, rigging setups, and holding items in place.

These shackles are available in several sizes starting from 1/4" up to 2", with matching working load limits ranging from 0.5 tons to 35 tons. They are made to fit well with hooks, chain, or wire rope when used for jobs that do not involve lifting heavy loads overhead. Each shackle is marked with its size and load limit to help with selection and setup.

At Holloway Houston, we stock round pin chain D shackles that are made by trusted manufacturers like Green Pin. These shackles are known for smooth surfaces, proper pin alignment, and steady sizing, which helps with fitting and reassembly. They’re often used in general rigging, transportation, and light-duty lifting where loads stay steady and don’t shift during use.

If you’re looking for a similar shackle with a different type of pin, Holloway Houston also offers screw pin chain D shackles. These shackles use a threaded pin instead of a round pin and may be better when the setup is subject to more movement. Both types come in the same body shape but serve different purposes depending on how often the connection needs to be opened or how the load is applied.

Round pin D shackles are helpful when you want a pin that won’t come loose easily. The cotter pin that holds the round pin in place adds extra safety in simple setups, especially where you may not be checking the hardware often. These shackles are often used in trailer chains, taglines, and support fixtures that stay in place for longer periods.

Holloway Houston also carries anchor shackles with round pins if you need a shackle with a wider opening. The anchor shape allows more room inside the body, which is helpful when you need to connect larger gear or use more than one link inside the shackle. Like the D shackles, these are sorted by size and load capacity to match different setups.

Each product page includes details like size, working load limit, and finish so you can quickly compare options. Common mid-range sizes include 5/8", 3/4", and 1-1/2", which are often used for equipment transport, spreader bars, or temporary anchors. For large jobs or fixed installations, sizes like 1-3/4" or 2" are available and easy to order.

Holloway Houston also offers shackle accessories such as replacement pins and cotters, which are useful when parts are lost or damaged. It’s important to match the pin to the shackle size to keep everything working properly.

These shackles are also marked with paint or stamps for size and load tracking. While color can help with sorting gear, we always suggest checking the markings for actual capacity details. This helps make sure the right hardware is used during setup.

Unlike screw pin shackles, round pin shackles do not need to be tightened with tools. Once the pin is in place and the cotter pin is set, the connection is ready to use. This makes them easier to handle in the field, especially if you're working in tight spaces or need to move quickly.

For jobs where rigging changes happen often or where the load doesn't move around much, round pin D shackles are a good option. They can be used in lifting plans that don’t involve angles or shifting weight. Some common uses include suspension of light equipment, temporary fencing, or tying down cargo.

To keep your shackles working well over time, check them regularly for wear, rust, or pin damage. Wipe them down when needed and keep the pin holes clean so the cotter fits properly. In humid or coastal areas, it helps to apply a bit of grease to prevent buildup and make the parts easier to remove later.

If your project involves strong forces, sudden shifts, or heavy vibration, Holloway Houston also stocks bolt type shackles that hold the pin more firmly using a nut and cotter pin setup. These are better for long-term lifting or applications where the load moves during use.

You can also browse master links, lifting points, and chain slings on the Holloway Houston website if you need more gear to complete your lifting or pulling system. These items work well with round pin shackles and are grouped by load limit and size to help you build a complete setup.

Round pin chain D shackles are often chosen for their simple design and easy pin system. Whether you're putting together a basic rigging kit or tying down loads for transport, these shackles offer a practical option for steady jobs that don’t require constant pin adjustment. At Holloway Houston, we keep each size ready to ship and easy to reorder, making it easier for your team to stay prepared.
