We've been sourcing these leveling systems for about three years now, and what really makes them worth buying is the clip reusability—most crews get four or five uses before they start to fatigue, which is better than the cheap single-use stuff we tried earlier.
The polymer blend in the clips has a tighter tolerance than most generic spacers, typically holding within 0.1mm across the 1.0mm, 1.5mm, 2.0mm, and 3.0mm sizes, and the stainles steel wedges don't warp under the pliers presure even after repeated use.
One thing we learned the hard way is that these clips aren't great for very thin porcelain (under 6mm) because the tension can micro-fracture the edge—so we usually recommend the 1.0mm size for those jobs, or just stick to ceramic.
The carton dimensoins for clips are 54×38×35cm, which is actually a bit bigger than you'd expect for 100 pieces, but that's because they're nested to prevent bending during shiping, and the wedges come in a separate 47×32×20cm box.
Lead time is roughly 20 days or so for a standdard order of 500 bags, but we always confirm stock before quoting because the 3.0mm clips sell out faster than the others—most buyers go with the 2.0mm for general floor work anyway.
operating temperature range of -20°C to 60°C hasn't been an issue for us even in cold warehouse conditions, though we did have one shipment where the clips got brittle after sitting in a frozen truck for two weeks (check lead time if you're ordering in winter).
We usually require a MOQ of 50 bags per size, but for first-time orders we can negotiate down to 20 bags. Just reach out to confirm.
For stock orders, lead time is about 7-10 days. Custom packaging or mixed sizes might take up to 15 days.
Yes, we include a copy of the ISO 9001 certificate with every shipment. If you need a specific format or notarized copy, just let us know.
Officially rated for 5 uses, but many customers push them to 6-7 times if handled carefully. The polymer does wear down, so we recommend replacing them after 5 uses for consistent leveling.
Yes, they work fine with natural stone as long as you don't overtighten. The 1.0mm gap is standard for stone, but if your tiles are uneven, going with 1.5mm gives you more room to adjust.
