Dryer you can post a photo, but that sounds about right. The aluminum alloys they use combined with the shape makes for some pretty awesome devices. However the formula F=ma force = mass times acceleration is a sort of momentary thing (with acceleration as a variable) vs "holds 4500 pounds. It probably will hold 4500 pounds, (its the same amount of force) but thats not an important thing to climbers who are worried about impact. That said Camp produces junk, pardon me. Others will argue, but theres a reason why its $6.00. I have here a black diamond wired beener in my hand that says 24 kN along the axis, 7 kN perpendicular to the axis and 8 kN along the axis with the gate open. Ya see with the gate closed its essentially a ring.
