Ball Bearing Push to Open Drawer Slide JL-451021 for Kitchen Cabinet Drawers with 45kg Load Capacity

We're shiping these out in 250mm to 600mm lengths, and the 45kg load capasity handles a fully stocked kitchen drawer without any sagging — it's pretty much standard for heavy-duty use. The zinc-plated finish on hardened cold rolled steel means you don't have to worry about rust in a humid cabinet setting, which is actually a common issue with cheaper slides.

Basically, you push the drawer to open it, and it pops forward smoothly on steel ball bearings — no handle needed, just a clean, flush front. Most buyers go with teh 300mm or 450mm for standerd kitchen cabinets, but we can customize the length if you need something in between.

It's a two-knot structure, which is better than single-knot slides for stability under load, though it does make the slide slightly heavier — about 1.2kg per pair for the 450mm version. We usually have stock on common lengths, but confirm lead time for custom sizes (usually 2-4 weeks or so).

A detail you might not think about: push mechanism is tuned to trigger consistently even when the drawer is loaded unevenly, but it's not suited for drawers wider than 900mm without additional support. One buyer tried it for a heavy file cabinet and it worked, but we'd recommend checking the weight distribution first.

Also, the COA form our Guangdong facility covers hardness and zinc thickness, and our company can provide it with the shipment — we've had labs verify it at 48-52 HRC on the rails. It's a tighter tolerance than some generic import slides, which tend to wear out faster in high-traffic kitchens.
