Betesy Hardware 1 Pair of 48 Inch Heavy Duty Drawer Slides 500LB Full Extension Side Mount Ball Bearing Drawer Rails

I built a bed in my sprinter that slides out to be a queen size bed. These work great, and are super sturdy. We went on a month long trip around the country and they still perform. They cannot be taken apart, so you do have to come up with an assembly sequence that works for you purpose. It isn’t like building regular cabinets and sliding the drawers in.

I built a custom drawer unit for the bed of my 2020 Nissan Frontier. I added a second pull put tray for easier access. These worked perfectly for what I needed. The quality seems great so far and they slide nice and smooth. They came shipped in ehh sorta crappy package dor the weight but my 54 inch slides did show up undamaged. I like the locking feature these have.. in my photo it is showing about 170 lbs of weight at full extension and they don't sag or bind.

After much planning I finally built the truck camper shelf/bed/drawer setup for a trip and these slides worked great. They’re very burly and the action on the slide is both smooth and confident. However! The packaging was crap and both release levers were bent (thus 4 stars) - I bent them back n they worked just fine on my 10 day trip vs returning. Glad I kept them. The directions were both tiny n poorly written with the exception of very good idea to use thin spacers under the drawer to keep it suspended while installing slides - I bought the screws I needed. One catch - the drawer locks halfway when closing so you have to depress just the RHS lever to get it to close all the way.

I replaced my old flimsy slides in my off-road trailer with these. Huge difference. They are very heavy duty. Easily holds up a 75qt and a sink and dual burner stove.

6 foot truck bed drawers.. these really work and really do hold a ton of weight. I ended up with drwaers that are about 23 inches tall, almost higher than the tailgate and all the way back in a 6 foot bed. I then fill them full of tools and close them shut. Inclicp and they roll out like butter. Done be afraid to get slightly shorter ones, you really don't need the full length because when you pull ouytthe 52" ones all the way you can still easily reach to the back of a 6 foot drawer and grab what you need. These work just fine for me on my 6 foot bed even when full of 300 lbs of tools.

I used these to make a slide out storage area on my fifth wheel. Works great and gives great access to the area behind my tool box

They work, and are fairly smooth. Not sure they’d actually support the advertised weight.

The drawer slides are used in my camper. They are very solid and the locks work well in both the extended and retracted position.
