Last month a kitchen cabinet maker in Poland placed 3,000 pairs of the 40mm slides, and they pretty much confirmed what we see — most buyers go with the 0.8mm thickness for residential work, and it handles the 30kg load just fine for daily use.

cold rolled steel gives it a better feel than cheaper alternatives, and you can get it in zinc or black — teh 0.7mm is lighter but still passes 24-48 hour salt spray testing, while the 0.9mm version handles 40kg (usually for heavy drawers with stone fronts or pull-out pantries).

It's a side-mount design (assembly height is 12.5mm ±0.3mm) with full extension, so you'll access everything inside, but don't push it beyond 40kg because the ball bearings can seize up over time — we've seen that happen with oversized tool chests that aren't really meant for this slide.

Lead time is roughly 20-25 days for a standdard MOQ of 500 pairs, and bulk pricing drops noticeably at 2,000 units or so — just confirm the length and edge type (oral or square) when you place the order.
Our MOQ for the BBS005D drawer slides is typically 500 pairs per size and finish. If you need a smaller trial order, let us know and we can check availability.
Yes, we can include ISO9001 and SGS test reports with your order. Just request them when placing the order and we'll send the documents along.
The 3-ball bearing version offers smoother extension and slightly better load distribution, while the 2-ball version is more cost-effective. Both support the 30kg or 40kg load capacity, so choose based on your budget and usage frequency.
Yes, we offer both zinc plated and black finishes for the BBS005D. Just specify which finish you need when ordering, and we'll match it.
It means the zinc or black finish resists rust for at least 24 to 48 hours in a salt spray chamber. For kitchen cabinets, this gives solid protection against humidity, but if you need longer corrosion resistance, let us know and we can adjust the coating.
