Surprise, AZ (PressExposure) July 11, 2011 -- C-Mack Supply Co., the one-stop-shop for all rigging and lifting hardware has expanded its information base and added new information about shackles (http://cmacksupply.com/shackles/).
Shackles are U-shaped metal devices that are used as a connecting link. These are metal devices that make use of clevis pins or bolts to enclose the opening. There are different types of shackles that are used for different applications. These metal devices are typically used for lifting and rigging.
There are round pin anchor, screw pin anchor, snap, chain, headboard, twist and bow shackles. Carabiners that are used for wall climbing or mountaineering are actually snap shackles.
The type of pin that secures the shackles varies as well. There are normal pins and threaded pins. Those that do not make use of pins feature a quick-release mechanism.
One can easily spot different types of shackles used on ships. Halyards that are used to hoist a sail make use of these metal devices. One can see either a twist shackle or headboard shackle on a halyard.
Choosing the right shackle for a particular task is important. Each of them is made for a specific purpose. The type of closure, pin diameter and shape of the shackle should be considered prior to using it. Different loads and applications require a certain type of shackle. Using the inappropriate one can result in injury and a bent or broken shackle.
C-Mack Supply Co. (http://cmacksupply.com/) is happy to introduce this information to people who are looking for the right device to use for rigging and lifting. The website is a one-stop-shop for lifting and rigging hardware, but it also provides a brief introduction to the different devices that fall under this category. The website will continue to add information to make sure that one gets the right kind of hardware for a particular task.
