Our Mission: To protect, preserve and promote the natural integrity of Radnor Lake through land acquisition, environmental education and park support.
Chains up to 12 mm thick are generally portable: you can carry them around on your bike every day. The long ones will be really heavy though, so please check the weight. Above 12 mm the chains are more suitable as stationary locks: you would leave them wherever you lock your bike for long periods of time.
The WLL and lifting capacity increases as the grade increases. For example, a 3/8 inch Grade 80 chain has a WLLof 7100 pounds, a 3/8 inch Grade 100 chain has a WLL of 8800 pounds, and a 3/8 inch Grade 120 chain has a WLLof 10,600 poundsâ50% higher than Grade 80. For safety reasons, each chain and sling is rated with a 4:1 design factor. The 3/8 inch Grade 80 chain with a WLLof 7100 pounds is pull tested to 14,200 pounds and has a minimum breaking load of 28,400 pounds. Every chain or chain sling is only as strong as its weakest link, so it is very important that every component of the sling meets WLL.
