The YKK fastener of the LB-RC series can be the key element of your product.
It has a simple design with a curved surface and side opening, allowing one-handed operation and avoiding accidental opening.
Backpacks, belts, collars, harnesses, bracelets can be created with this versatile accessory.
On the one hand (“mother”), this fastex has one slot through which it is sewn to the belt tape.
On the other side (“father”) of the fastex, there are two slots into which the belt tape is threaded with the possibility of adjustment.
Fasteks LB15RC fits under the tape (sling) 15 mm wide. Fastex design guarantees strength and durability.
Fastex material – acetal (ROM).
Acetal (Polyoxymethylene) is a crystalline thermoplastic polymer material that is characterized by excellent tensile strength, rigidity, surface hardness and chemical resistance.
Acetal has excellent flexural memory and retention of properties when subjected to repeated loading.
The physical properties of this plastic remain unchanged over a wide range of temperatures, relative humidity and weather conditions.
Normal short-term temperature range of its use: – 40° C to + 132° C
When designing modern bags, backpacks, and urban accessories, manufacturers strive to use not only reliable but also ergonomic plastic hardware. A properly selected fastener improves ease of use, enhances appearance, and increases durability. The YKK LB RC series fastex buckle is a compact model with a side opening and features a curved body. This design allows the buckle to better conform to the shape of the product, sits more comfortably on straps, and takes up minimal space. The LB RC series is designed for compact backpacks, travel bags, luggage, and other items where compact size, reliability, and signature YKK quality are especially important.
What is the YKK LB RC series fastex buckle?
The YKK LB RC series fastex buckle belongs to the Side Release Buckle category—plastic fasteners with a side opening. The model’s key feature is its curved case, which allows the clasp to naturally follow the shape of the belt or flap, ensuring more comfortable use. This series is designed for compact products and is compatible with 15mm wide belts. The case is made of durable POM (polyacetal) engineering plastic, which is highly resistant to wear and mechanical stress. The model’s primary applications are: Backpacks, bags, and luggage.
Their compact size makes the LB RC series an excellent choice for items where standard large fastex buckles look too bulky or take up too much space.

How the LB RC Series Fastener Works
The YKK LB RC series fastener operates on a proven side-opening mechanism.
After the two halves are connected, spring-loaded latches engage in mating grooves in the housing and securely hold the plug inside the fastener. To open, press the side latches simultaneously, after which the halves easily separate.
High precision manufacturing ensures a smooth connection and minimal play during operation. This ensures the clasp maintains stable operation even after numerous opening and closing cycles.
The curved housing distributes the load on the strap more evenly and makes the product more comfortable to use, especially if the clasp is located on curved areas of a backpack or bag.
Design Features
The main feature of the LB RC is its combination of compactness and ergonomic shape.
It is made of polyacetal (POM)—a modern engineering plastic with high strength, resistance to abrasion, moisture, and temperature fluctuations. Thanks to these properties, the clasp maintains stable operation even with intensive daily use.
The curved housing surface allows the clasp to fit better on the product. This solution reduces protruding structural elements and creates a neater appearance.
The compact size is especially convenient for small bags, urban accessories, and items where maintaining minimal structural thickness is important.
High manufacturing precision ensures secure fit and smooth operation throughout the entire service life.
