RockLock™: The Patented Slab-Securing Technology Behind Our Safety Systems
RockLock™ helps reduce over-center tipping risk by stabilizing slabs during key stages of handling, from staging and transport to container receiving.
How RockLock™ helps
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
🛠 Container Receiving
Container unloading and first movement
🚚 Transport & Delivery
Pickup, trailers, and flatbeds
🏢 Warehouse & Yard
Fixed A-frames & storage racks
Fabrication & Installation
Slab unloading and installation movement
Safety Solutions from the Container to the Customer
Whether it be unloading bundles, hauling slabs over long distances, storing slabs in warehouses, or loading customer's pick-up trucks, Safe Stone Handling has you covered.
Choose the system that matches your setup, your workflow, and where slabs move
through your operation, from receiving to transport to storage.
Why Safety Directors and Executives Are Switching to Safe Stone
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
Built From Real-World Slab Handling Experience
Louwrens Mulder
Stone industry professional.
Creator of the patented RockLock™ safety mechanism.
Louwrens was originally tasked by the Safety Director of one of the world’s largest international stone dealers to design and build a safer Truck A-Frame for their fleet. After successfully completing that assignment, he decided to expand the patented safety innovations developed for the A-Frame across the entire slab handling chain, from the container to the customer.
Now, with your help, our mission is to make the stone industry we love a safer place to work.

One Mistake Can Cost Lives and Trigger Serious Liability
Stone slabs can tip when they move over-center, especially during routine staging, transport, and first movement during unloading. When handling relies on improvised supports or inconsistent tie-down practices, the risk increases, and the consequences can include injury exposure, product loss, downtime, and major liability.
Engineered controls help reduce that risk by creating a repeatable process that’s less dependent on perfect conditions.
“This is why safety systems must be engineered, not improvised.”
Examples of reported incidents in the industry:
Two workers crushed at Stone Warehouse of Michigan.
Huntsville Granite cited for fatal slab accident.
Semi-truck granite spill on I-24 causes massive delays.

FAQS
Will your systems work with my existing A-frames, trucks, or trailers?
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.
How does this help reduce tip-over risk and liability exposure?
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.
Do I need an A-frame already?
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.
Which system is strapless?
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.
