Featuring the patented RockLock™ Safety Arm System
Safe Stone Handling builds RockLock™ powered systems that reduce over-center tipping risk during warehouse staging, transport, and container unloading.
Not sure where to start? Most teams begin with Overhead Universal RockLock™ or Knockdown Safe A-Frame
Stabilizes slabs to reduce over-center tipping risk
Creates repeatable process control (less reliance on inconsistent tie-down habits)
Integrates into multiple systems (existing-frame setups and complete frame kits)
Built for real-world handling during movement, staging, and first unload

Stone slabs can tip when they move past over-center, especially during routine staging, transport, and first movement during unloading. Safe Stone Handling systems are built to reduce that risk with a repeatable process that supports safer operations and stronger incident defensibility.
✅ Reduce severe tip-over risk during critical handling stages
✅ Reduce slab damage and downtime caused by preventable incidents
✅ Support a more consistent safety process across teams and sites
✅ Improve defensibility after incidents with engineered controls vs improvised methods

RockLock™ was engineered to help teams reduce over-center tip-over risk with a repeatable, real-world slab-handling process.
“No one should have to risk their life to deliver or install a countertop or stone slab.”

Real-world risk scenarios, safer workflow tips, and product updates.
Industry updates for safety leaders, distributors, and fabricators.
Yes! Our systems are designed for easy “bolt-on” and HD Tie Down Chain Binders installation to fit most truck beds, semi-trailers, and even smaller transport equipment.
Our engineered systems dramatically reduce the risk of slab falls, which are a leading cause of injuries and fatalities in the industry. Investing in safer equipment protects your people, reduces worker’s compensation claims, and protects your bottom line.
Some systems work with existing A-frames (like Overhead Universal RockLock™). If you don’t have a suitable frame, the Knockdown SAFE A-Frame System includes a complete frame kit.
The Truck Safe Strapless A-Frame is designed as a strapless transport system. Other setups may still use tie-downs depending on configuration and application.
