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.
A standard double loop chain is often used for porch swings. Assuming three hefty occupants (~250 lbs each) and a 100 lb swing, you're up to a load of 850 lbs. If you use 4 lengths of chain to connect the swing, that's 212.5 lbs per chain.So you need at least 2/0 chain, which is rated to a working load of 255 lbs and an UTS of 1020 lbs.f you use 4 lengths of chain to connect the swing, that's 212.5 lbs per chain.
