Lifeline Olympic Bar and Bumper Plates

Does anyone have any more information on the bar? I’m wondering what the tensile strength is, and what kind of method is used to secure the sleeves, if it’s an end cap, snap ring, or bolt attachment.

The bar itself weighs 45 lbs. with a listed maximum capacity of 1000 lbs.

Spring collars are included with purchase of the bar.

Does this come with one bar and one plate? Or is it a set of 2 plates, e.g I order 1 45 and get the bar and one plate for $49.99? Or do I get a balanced set of 2 plates and a bar?

Each plate and bar are sold separately.
