Nice and strong. But I’ve never seen a pair of these that don’t have a separation lever between the first and second set of rails.

Excellent quality, holds a large generator no problem. Installation was fairly simple, great price and they lock in just like the should.

These have a nice solid feel to them. They are very sturdy. I built a slide out tray for my RV. It’s working great.

Slides are very robust and work well. However, they are difficult to install. There is no release for the drawer segment. You need to attach to the cabinet, extend the slides, then attach the drawer to the extended slides. This was tricky with the very heavy drawer I was installing. Also, no screws are included. I used #12 and #14 screws (the holes are different sizes for the case and drawer).

Where is satisfied with their strength or durability? Installation wasn’t bad but would be easier if the slides separated

These are very heavy duty slides that lock in place. I used them to mount an induction cook top in my camper van's kitchen. They were slightly tricky to mount as they don't separate, but that was a minor problem. They have a very solid feel and the locking mechanism is very robust. These slides weren't cheap, but I feel that they were worth the money.

Smooth slides. And easy to mount with the under mount style. And the full slide out comes in handy

I used these in a slightly unconventional way but they worked perfectly. I used them as drawer slides for a tray to hold an 85lb keyboard. I had issues with previous side mount slides so I actually used these as mounts on the top of the desk arm and underneath the tray itself. Finished project looks nice. Very heavy duty! Like many have said definitely add weight to the project. But they worked when I couldn't find anything else thay would.
