Drawer Slide, Full Extension, 24 in, Heavy Duty, 500 Lb. Capacity, Zinc by Hettich

These things are great! Very heavy duty and easy to install. I'm using them to pull out my sofa into a bed in my camper conversion. They hold mine and my husbands weight (and we're not light people) without any additional legs supporting the extended portion. The full width extended is 48 inches which makes for a nice full size bed in the van.

The 500lb capacity, of course, means you really should only use these if you plan on putting things over 100lbs on the drawer these slides are intended for, because the slides themselves are extremely heavy...

Replaced two overloaded ball slides on the front cap of our RV with these and they work like a dream and don't see them ever failing in the application.

They are beefy alright. Perfect for my project. They only thing I don't care for: They don't come apart so you can't remove the drawer or whatever you are attaching these to. I suppose that's not an easy option to have with 500 pounds rails so this is less of a 'problem' as 'be aware' -this only way you are getting the drawer or whatever out it to unscrew the until from the rails.

Built a pretty amazing shelf above the refrigerator. Only ting I would have done differently is bump them out from the wall by an 1/8 of an inch by backing it with a very thin laminate. If the wall is not perfect, which my plasters walls are not, it can scrap because there is only 1/16 inch clearance for the slide.

We used these to make a slide outcouch bed in our skoolie conversion. They hold the full weight of a person without any legs or supports underneath. These are awesome!

Not sure how you're supposed to mount the stationary side. There is no clearance for a bolt, screw or rivet.

Dope slides, used them for 400lbs of batteries in my skoolie
