This wide mouth slide buckle, also known as a tri-glide buckle, is specifically designed for applications requiring easy adjustment of thicker or heavy-duty webbing. With an enlarged inner length, the wider slots accommodates webbing with greater thickness while still allowing smooth length adjustments. This makes it an excellent choice for rugged gear that demands both strength and versatility.

For enhanced grip, the middle bar on the front side features an anti-slip stripe design, while the outer bars on the back side also incorporate textured stripes to prevent webbing from loosening under tension. This ensures that your straps remain securely in place, even in demanding outdoor or industrial environments.

Typical Applications:

  • Pet collar buckle – Perfect for heavy-duty dog collars and harnesses

  • Backpack strap buckle – Ideal for hiking packs, travel bags, and tactical gear

  • Medical sling adjuster – Ensures secure and comfortable patient support

  • Garment accessories – Used in belts, shoulder straps, and workwear equipment

Key Features:

  • Wide mouth design – Fits thicker webbing with ease

  • Durable construction – Made from high-quality POM (Polyacetal) plastic for strength and weather resistance

  • Secure grip – Anti-slip stripes reduce slippage and improve stability

  • Multi-purpose use – Works as a tri-glide webbing adjuster for both indoor and outdoor gear
