If you need a shackle for your operation which complies with British Standards, you have come to the right place. This British standard screw pin large dee shackle is available in a wide range of sizes with working load limits up to 20 tonnes.
Why choose the British Standard Screw Pin Large Dee Shackle?
These specific dee shackles incorporate a standard screw pin opening to enable quick and easy fitting. After hand tightening the screw pin it is wise to further crank the pin with another tool such as a pair of pliers or a screw driver through the hole. This is to ensure the maximum tightness is achieved to alleviate the threat of un-screwing.
This Dee shackle conforms to BS (British standard) 3032 table 2; so you can be assured of a quality and safe lifting shackle. We can also supply these shackles in a small dee variety or a British standard screw pin large bow shackle.
