⚙️ Angle Grinder Resistant Construction

The RockSolid uses a proprietary blend of ultra high-strength materials, reinforced with a multi-layered defensive structure designed to wear down grinder discs and dramatically slow cutting attempts.

• Diamond-coated shackle resists abrasive cutting

• Hardened, shrouded shackle design limits access for grinder blades

• Engineered structure disperses heat and cutting force

• Built to withstand repeated brute-force attacks

This is true angle grinder resistance, not marketing fluff.
