Product Description

LK-U YKK is a three-slot regulator buckle designed for reliable fixation and quick adjustment of the length of textile belts, slings and tapes. The three-slot design provides more accurate and stable adjustment, including in dynamic conditions: when moving, loaded, changing the position of the tape.

Advantages of the adjuster buckle

  1. Absolute reliability.YKK products undergo strict quality control. LK-U demonstrates resistance to stretching, deformation and wear during long-term use.
  2. Convenient length adjustment. The three-slot design provides excellent fixation of the tape, eliminates its spontaneous displacement even under vibration, running, load.

  4. Environmental resistance. The adjuster buckle is not afraid of moisture, dirt, frost, UV radiation. Maintains properties in the temperature range from -40°C to +85°C.
  5. Safety.The absence of sharp edges and burrs makes LK-U safe for textiles and the user. Can be used even on children’s or medical products.

Recommended use

  • Choose the LK-U size depending on the width of the tape. Excessive looseness or tension will compromise the fixation.
  • Use with polyester or nylon tapes for better friction and fixation.
  • Avoid mechanical damage: do not hit the buckle with heavy objects.
  • Do not use as a safety element during mountaineering and rescue operations.
  • Periodically clean the product from dust and sand to maintain ease of movement and tight fixation.
