💡 How does full surface continuous mounting affect structural integrity during repeated impact cycling?
You grab this gear when standard hardware buckles because it shifts door weight away from weak corners straight into the solid frame.
- Distributes shear forces across many attachment points so torque never breaks weld seams during crash testing
- Interlocking ratchet tracks absorb kinetic energy and prevent deadbolt misalignment after years of hard hits
- Is really handy for warehouse bays since you patch old framing without installing extra reinforcement channels
