Metal Side Release Buckle Plus – Brass Plated
The buckle features openings that are 0.5 to 1 mm wider, enabling seamless use with our waterproof straps. Load testing has also shown that this version achieves on average 30 to 50 kg higher strength than the original model. Thanks to its more rounded design, improved mechanism, and a wide range of 6 sizes, it is suitable for the production of collars, straps, backpacks, bags, and other leather goods.
How to care for the hardware
Even hardware needs basic care. Watch the video where we show how to maintain it so it retains its functionality for as long as possible.
Notice:
We do not recommend washing products with this hardware in a washing machine or drying them in a tumble dryer. If the product gets wet, we recommend drying it thoroughly. Prolonged exposure to moisture is not suitable for the internal fastening mechanism. At low temperatures, zinc alloy may be more sensitive to impact, so we do not recommend exposing frozen hardware to shocks or rough handling.
Surface finish: Brass plated
Expert's opinion
Pavla Nováková
Craft isn't just about feel – it's about understanding the material and the process. If it works in my workshop, it'll work in yours.
I see metal side-release buckles primarily as a design upgrade. Compared to plastic, they give the finished product a more premium feel and visual consistency – especially when matched with a D-ring and other hardware in the same finish. This visual coherence is exactly why I reach for them.
From a production perspective, it’s important to distinguish between the two available versions. The Plus variant, thanks to its wider openings, easily accommodates thicker or layered materials, while with the basic version it’s necessary to keep an eye on material thickness and make sure in advance that the selected strap will pass through smoothly.
Since this is zinc alloy with a surface finish, the hardware does require a bit of care. I wouldn’t put these buckles in a washing machine or tumble dryer, where both the finish and the internal mechanism can suffer. It’s also fair to expect that metal-on-metal contact will occasionally produce a slight clinking sound, which may not suit everyone.
I choose the metal version whenever an elegant look and well-matched details are the priority. Plastic, on the other hand, works better where lightweight construction, practicality, and quiet operation come first.
I evaluate objectively what others only guess.
