The fastex clasp YKK of the LB-RS series is distinguished by its convenient shape and high tensile strength.
Designed for detachable connection of belts and slings.
It has a simple side-opening design that allows one-handed operation and avoids accidental opening.
Fasteks LB-RS fits under the tape (sling) 20, 25, 38 mm wide.
The range of application of fastex is quite wide. It can be: backpacks, shoes, belts, bags, paracord bracelets and much more.
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.
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.
The normal short-term temperature range of its use is – 40° C to + 132° C.
Modern plastic hardware must not only be reliable but also as compact as possible. Manufacturers of bags, backpacks, clothing, and sports equipment are increasingly choosing solutions that reduce product thickness, maintain an attractive appearance, and ensure ease of daily use. The YKK LB RS series fastener meets these requirements. This model features a thin and short design, light weight, and an original, smooth-operating side release system. Thanks to YKK’s thoughtful engineering, this fastener is successfully used in a wide variety of textile products—from urban accessories to camping gear. The LB RS series is designed specifically for applications where compactness, ergonomics, and high reliability are essential.
What is the YKK LB RS series fastener?
The YKK LB RS series fastener belongs to the Side Release Buckle category— Plastic side-opening clasps. The key feature of this model is its slim, shortened body, which takes up minimal space and barely protrudes above the surface of a belt or textile.
Another distinctive feature of this series is the unique design of the side levers. They are designed as hinges, allowing for a smooth opening and requiring less effort than many traditional plastic clasps. This solution makes use more comfortable, even with frequent opening and closing.
The buckle is available for 20, 25, and 38 mm wide belts and is made of durable POM (polyacetal) engineering plastic.
Advantages of the YKK LB RS Series Fastex Buckle
The high popularity of the YKK LB RS Series Fastex Buckle is explained by its combination of compactness, reliability, and ease of use.
The main advantages of the model:
- slim design;
- reduced overall length;

How the LB RS Series Fastex Buckle Works
The YKK LB RS series fastex buckle operates on a classic side-opening mechanism.
After the two parts are connected, spring-loaded locks automatically engage the corresponding grooves in the housing and securely hold the plug inside the buckle. To open, simply press the side levers.
The main difference with the LB RS series is the design of these levers. They have a loop-shaped design, distributing the force more evenly. As a result, the buckle opens smoothly and softly, while remaining resistant to accidental unfastening. This design is especially convenient for regular use.
The compact geometry of the case allows for a shorter clasp length without compromising the strength of the connection.
Design Features
One of the key features of the LB RS is its combination of minimal dimensions and high strength.
The case is made of polyacetal (POM)—an engineering material characterized by high mechanical strength, abrasion resistance, moisture resistance, and temperature fluctuations. Thanks to these properties, the clasp maintains stable operation even after extended use.
The thin profile makes the product more comfortable and reduces protruding elements. In addition, the reduced body length has a positive effect on the appearance of the finished product.
The precise geometry of the parts ensures a tight connection between the fastener halves and virtually eliminates play during use.
