These are excellent slides. They do live up to the Heavy Duty tag on them. Mine are loaded with about 200lbs on them and there's no deflection, wobble, or any indication that they have any give. I used these to make a slide out drawer for a spindle sander and tools. It slides out and then has a fair amount of force applied to it when it's fully extended. I'm pretty happy with these.They do come with some hardware but it's only good for installing into a steel cabinet. If you're installing into a wood cabinet or something other than a sheet steel cabinet then you'll need to get your own hardware.
