Model: CK603
Material: POM
Product specifications: 20mm、25mm、32mm、38mm、51mm
Modifiers: durable, convenient, multi specification, high-strength
Usage: Mainly used for connecting and opening backpacks, outdoor equipment, luggage and other items, achieving quick assembly and disassembly, and can also be used in some scenarios that require temporary fixation or quick connection.
A small hardware piece, big practical payoff. The Double Concave Monotonic Buckle CK603 is a precision-molded POM fastener engineered to make connections simple, secure and repeatable. Composed of a male tongue and a female socket with an internal locking geometry, the buckle clicks together in one motion and releases cleanly when needed. It comes in five webbing widths (20–51 mm) so designers and end-users can pick the right fit for backpacks, luggage, outdoor equipment or child products. The material choice—POM—gives the assembly a smooth, slightly satiny feel, excellent dimensional stability, and resistance to abrasion and many common solvents. In use you’ll notice the satisfying tactile click when engaged, a low profile that sits flush with straps, and confidence that the connection will stay put through day-to-day movement.
This buckle is designed to make life simpler for product designers, packers, and users:
Fast, reliable connections: One-handed or two-handed engagement that locks securely — so users spend less time fumbling and more time doing.
Durable POM construction: Resists wear and keeps its shape season after season — translates to fewer replacements and lower lifecycle cost.
Multi-size availability (20–51 mm): Flexibility to match various webbing widths — avoids the guesswork during procurement or retrofitting.
User-friendly release: Smooth, predictable unlocking reduces frustration and supports quick adjustments in the field.
Versatile application range: From hiking backpacks to luggage straps to children’s carry items — a single buckle covers many product lines, simplifying inventory.
POM is chosen for stiffness, dimensional stability and abrasion resistance.
Long wear life in repetitive fastening cycles.
Stable under temperature swings typical of outdoor use.
Male tongue + female locking slot ensures positive engagement.
Low-profile geometry reduces snagging.
Locking geometry engineered to prevent accidental release under typical loads.
Five standard widths cover common webbing options.
Easier SKU management for manufacturers.
Quick retrofit into existing strap systems.
Everyday convenience is prioritized.
Fast snap-in action; deliberate and effortless release.
Predictable feel for end-users, including children and seniors.
Fits consumer goods and light commercial uses.
Ideal for backpacks, luggage, outdoor gear, children’s products.
For safety-critical uses, recommend testing in the final assembly and verifying against local standards.
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.
