Фастекс LB-LS

When producing modern equipment, clothing, accessories, and compact textiles, choosing the right plastic hardware is crucial. Standard fasteners are often too large and heavy for thin cords and small straps. That’s why YKK developed the LB LS Fastex—a miniature plastic fastener designed for use with 0.8 mm diameter cord. Despite its small size, this fastener provides a secure fit, ease of use, and a long service life. Its compact design makes it popular in the production of sportswear, accessories, camping gear, and other products where minimal weight and a neat appearance are important.

What is the LB LS Fastex?

How the LB LS Fastex works

The LB LS Fastex operates on the same principle as classic side fasteners.

After the two parts are connected, the spring-loaded side locks engage the corresponding grooves in the housing and securely hold the plug inside the lock. To open, simply press the side latches simultaneously, after which the clasp easily disengages.

The design is specially optimized for attaching a thin 0.8 mm diameter cord, ensuring a neat, easy, and secure connection.

Design Features

The main feature of the LB LS is its miniature body.

Its construction is made of POM (polyacetal) engineering plastic—a material characterized by high mechanical strength, abrasion resistance, moisture resistance, and temperature fluctuations. This ensures the clasp maintains stable operation even under daily use.

The compact design allows for use in spaces with limited space. The minimal dimensions also make the fastener virtually invisible on the finished product, which is especially important for modern clothing and accessories.

An additional advantage is its light weight, which has virtually no impact on the weight of the finished product.
