1. Core Hardware Setup

• Heavy-duty Single Tongue/Prong
  Thickened stainless steel forged tongue—won’t bend or snap. The tip’s smooth, so it won’t cut the webbing, slides in/out easy, and fits those tight holes on leg adjustment straps.

• Reinforced Buckle Frame
  One-piece stamped/die-cast—no weak weld spots. Wider sides fit standard 45–50mm strong safety webbing.

• Matched Metal Eyelets
  Pairs with thick metal riveted eyelets on leg straps (stops tearing/hole stretching). Once the tongue’s in, it won’t slip out or come undone.

• Anti-Accidental Release Stop
  No wobbling or slipping off—when your legs jostle during high-altitude work, the tongue stays put. Some premium models even have hidden locking springs.

2. Safety Load & Materials

• Material: High-strength alloy steel—skip cheap zinc alloy (it’s brittle and won’t stop falls).

• Breaking Strength: Single buckle handles ≥15kN static pull (CE fall protection grade)—good for catching you if you fall.

• Corrosion/Rust Proof: Salt-spray resistant—no rust or jamming, even for outdoor, construction, wind power, or curtain wall work.

3. Adjustment Features (Leg Straps Only)

• Continuous Fine Tuning
  Adjusts to your thigh size and how tight you want it. Squatting, climbing, or hanging? No pinching, slipping, or shifting.

• Self-Locking Webbing
  After adjusting, the strap locks in place—won’t slowly loosen under pressure. No more worrying about leg straps coming undone up high.
