Model: CK613
Material: POM
Product specifications: 16mm、20mm、25mm、38mm
Modifiers: Durable, Enhanced, Convenient, Multi Specification
Usage: Mainly used for connecting and opening backpacks, outdoor equipment, luggage and other items, achieving rapid assembly and disassembly, especially suitable for scenarios with high requirements for connection strength.
The CK613 is a precision-molded, double-concave adjustable buckle crafted from POM, engineered for situations where both adjustability and connection strength matter. Its double-adjustable design lets users easily alter strap length on both sides of the buckle without re-threading—ideal for backpacks, tactical gear, luggage straps, and any application that must adapt quickly to changing loads or body sizes. Built-in locking geometry secures the webbing and resists slippage during movement, while the double-concave profile reduces pressure points and prevents fabric bunching. In everyday use you’ll notice a smooth feel where the strap passes through, a reassuring tactile “bite” when the webbing seats, and minimal creep once tensioned. The result is a fastening component that reduces micro-adjustments, keeps loads stable, and makes life easier for designers and end-users alike.
Rapid adjustment without disassembly: Double-adjustable layout allows quick tuning of both strap ends so users can adapt fit in seconds — important for rushing parents, outdoor enthusiasts, and field operators.
Secure hold under load: The engineered locking surfaces grip webbing securely to minimize slippage, delivering stable loads and fewer surprises during movement.
Durable POM construction: POM resists abrasion and environmental stress, so the buckle keeps its form and performance across many fastening cycles — lowering replacement and warranty costs.
Smooth webbing flow: Concave channels reduce friction and snagging, making adjustment smoother and quieter.
Universal sizing options: 16–38 mm widths cover a broad set of applications, simplifying procurement and SKU decisions.
1. Mechanical function & ergonomics: Double-adjustability plus concave channels promote ergonomics and reduce fabric caught at edges.
Outcome: Faster user adjustments and less wear on webbing.
2. Materials & durability: POM gives dimensional stability and abrasion resistance.
Outcome: Longer part life and predictable performance over seasons and use-cycles.
3. Load & stability characteristics: Locking geometry is designed to prevent unintended release and slippage under normal use.
Outcome: Safer transport and reduced re-adjustments.
4. Compatibility & integration: Four standard widths (16/20/25/38 mm) fit the majority of consumer and light-commercial webbing.
Outcome: Easier BOM matching and fewer special-order parts.
5. Applications & compliance: Suited to backpacks, luggage, outdoor and children’s gear — for safety-critical systems, test the complete assembly per local regulations.
Outcome: Clear guidance for QA and regulatory planning.
Widely used in outdoor products (such as hiking bags, camping equipment), luggage (such as suitcases, backpacks), children's products (such as children's backpacks, safety seat accessories) and other fields.
It consists of a male buckle and a female buckle. The male buckle has a tongue structure, and the female buckle has a corresponding slot and locking device. By inserting the tongue into the slot and locking it, the connection and fixation are achieved. The structure is simple but the buckle is stable.
