WB-S
Plastic hardware plays a key role in the production of backpacks, bags, camping gear, sportswear, and workwear. The quality of the fasteners determines ease of use, secure strap retention, and the durability of the finished product. The WB S fastener is designed for users who value durability, easy adjustment, and reliable operation for years to come. This model is a modern YKK plastic belt buckle and features a specially designed adjustment bar that prevents strap slippage. Thanks to thoughtful engineering, the fastener combines secure retention, ease of use, and high wear resistance.
What is the WB S fastener?
The WB S fastener is a plastic side-release buckle designed for quickly connecting and disconnecting straps. The model is available in several versions for 20, 25, 30, and 38 mm wide slings, making it suitable for a wide range of textile products.
The key design feature is the movable central crossbar, which provides a more secure fit. When tensioned, the belt is additionally pressed, which significantly reduces the likelihood of it slipping even during long-term use.
Another feature of the model is the proprietary W-shaped spring design, thanks to which the clasp opens easily when pressing the side fasteners, while maintaining high security when closed.

How the WB S mechanism works
The main feature of the WB S fastex is the combination of a secure lock and an effective belt retention system.
After the two parts are connected, the spring-loaded side clips automatically engage the corresponding grooves in the case, ensuring a secure fit. To open, the user simply presses both side elements simultaneously, after which the fastener easily disengages.
The movable central crossbar plays a special role. When the webbing is tensioned, it increases the clamping force, ensuring that the strap is held significantly more securely and virtually does not shift under load.
The use of a proprietary W-shaped spring allows for smooth and comfortable opening while maintaining a high level of connection reliability.
Design Features
One of the main advantages of the WB S Fastex is its carefully designed construction.
The body is made of polyacetal (POM)—an engineering material that boasts high mechanical strength and is resistant to impact, abrasion, moisture, and temperature fluctuations. Thanks to these properties, the fastener maintains stable operation even after prolonged use in challenging conditions.
The adjustable adjustment bar helps securely hold the strap, which is especially important when using backpacks, bags, and other equipment subject to constant dynamic loads.
The thoughtful body shape also reduces the likelihood of accidental snagging on clothing or equipment.
