This is a 1-pair set of 53 mm wide, lockable, three-fold (full-extension) drawer slides. They’re sold for RV drawers and industrial tool boxes.I mounted them in the truck on a plywood tray to make a slide-out so tools are easier to reach. That’s a real test: weight, vibration, and weather, not a kitchen drawer. They held up. Travel is smooth, they lock when extended or closed like they should, and they don’t feel like light-duty furniture slides.The worry at this price is usually thin steel and sloppy ball bearings. These don’t have that. The rails are stout, the lock catches with a positive click, and the pair stays aligned if you mount them square and use enough screws into real structure—not just thin paneling.They’re still only as good as the install. Measure length, keep both sides parallel, and support the load. A pair is two slides, not a complete drawer. For a homemade truck or box slide-out, they’re a cheap way to get locking full extension without buying a branded cargo system.Simple, sturdy, and they do the job. Highly recommend.

I bought them to make a sliding platform for my truck and they hold up really well. They're very sturdy, full extension, and the yellow button lock works 100% so it doesn't slide back on its own. For the price and how strong they are, they're totally worth it.

This would be useful for a contractor to use on a roll out tailgate drawer but in my case, I used them for a wide workshop tray to hold heavy tools. I put nearly 75 lbs on them including the drawer tray and had no problem with flex or resistance when rolling. This worked perfectly even with a heavy load in the drawer. The locks held the drawer closed or open very securely at both limits of travel and actuated easily with the large comfortable to use yellow finger handles. The ball bearings move smoothly and with little to no noise. I am very happy that the manufacturer gave a detailed tab drawing showing all applicable dimensions including the drawer lock that adds about 2” to the overall slide length. That said, there were no included paper directions in the box, so be sure to refer back to the listing page for reference. This effort serves the customer and seller well, and ends confusion on what size to order, but a paper copy would be helpful. Specifications are important and they did this well! Really well made slides and worth their price. Engineered with excellence in mind and great construction throughout. Even the packaging was well done with a cap at the end to protect the lever locks in shipment. 23.5" for the rail length alone and 24.75" with the lever lock handles included for reference.

I’m planning a “van life” style camper van. I needed something heavy duty, like *very* heavy duty. These will work. These would be good a truck bed storage system, a pull-out RV camper kitchen, or anything else, really,They’re built out of thick steel and they claim they’ll support up to 265 pounds per pair.The locking system allows you to lock the drawer in place when it’s closed, so it won't fly open while you are driving. They also lock at full extension, so the drawer doesn't accidentally slide shut when you have it open.The rails are rust and corrosion resistant, this is good for garages, workshops, or outdoor truck beds. Oh, and vans…Caution: These are industrial-grade rails, they are thicker than basic kitchen drawer slides. Make sure you measure your side clearance very carefully before building your drawers to accommodate the extra width.

The 53mm Wide Lockable Heavy-Duty 3-Fold Drawer Slides for RV & Industrial Tool Boxes 1‑Pair(2 Pcs) Are a solid, nice sliding set of drawer slides. Seem to be decent material and no issues on the slide for me.

These drawer slides feel genuinely heavy duty. The steel is thick, the extension is smooth, and once mounted they have very little side-to-side play.The lock mechanism is useful for a toolbox, RV drawer, or anything that moves around and needs to stay shut. At 28 inches they’re substantial, so I’d double-check the available depth before ordering.They’re heavier than standard cabinet slides, but that’s exactly what I wanted from them.

53mm Wide Lockable Heavy-Duty 3-Fold Drawer Slides for RV & Industrial Tool Boxes (2, 28)Brand: LUVHAUSERThe seller Luvhauser sells many models and sizes of drawer. I have their products to be well made, easy to install and have stood well when subjected to hard use. The 28 inch Lockable 3-fold Slides will support 265 pounds and are designed to support large drawers. These slides are the full extension type and will support the above weight if the surrounding structure is strong enough, with the drawer fully extended. Although a "datasheet" with needed clearances is currently included on this product page group, my slides arrived without any instructions whatsoever. Other drawer slides purchased from this seller did have instructions and data sheets. This particular product line appears to be a new item for LUVHAUSER and I might have received an early production example. I strongly recommend you take a screen shot off either the information in my attached photo or from the page now attached to this product page.Other attached photos may be of help when sizing slides for your use. My 28" slides, for example, are 28" but the extremely well made locking handle extends the total length to approx 29". This lock with the attached handles provides a very strong positive lock and are extremely easy to unlock. But you must account for them with your placement and drawer design. LUVHAUSER drawer kits usually come with decent quality screws designed to fit the slides. My pair came with screws and nuts. The screws are quite short at 7/16". I believe they are actually metric screws but the point is they seem to be designed to attach to metal brackets, not wood. LUVHAUSER does have metal end brackets suitable for use with their older drawer slides but I could not find any information concerning brackets for this particular slide. You might need to provide your own screws if you plan to attach these slides to wood as I do.If you plan to make large drawers and fill them with heavy loads, I believe these slides will provide years of service and are reasonably priced.
