Start With the Right System
Choose the system that matches your setup, your workflow, and where slabs move
through your operation, from receiving to transport to storage.
Overhead Universal RockLock™
Overhead Universal RockLock™
Best for:
Pickup trucks, utility trailers, and warehouse setups with an existing A-frame.
Requires an existing A-frame.
Key benefits:
Works with existing A-frames to help reduce over-center tipping risk
Fast to deploy for daily movement, staging, and handling
Helps create a more repeatable safety process without relying on perfect setup conditions
Universal Knockdown SAFE A-Frame System
Overhead Universal RockLock™
Best for:
Operations that need a complete A-frame system shipped as a kit.
Includes a knockdown A-frame kit.
Key benefits:
Ships as a knockdown frame kit assembled on-site
Mobile and warehouse configurations to match your operation
Ideal when you need standardized frames for safer staging and storage workflows
Truck Safe Strapless
A-Frame
Truck Safe Strapless A-Frame
Best for:
Flatbed transport where shifting and strap failure increase risk.
Key benefits:
Strapless mechanical compression system designed to reduce slab shifting
Built for stability under vibration, starts/stops, and road movement
Engineered A-frame approach for demanding hauling environments
Strapless mechanical compression system designed to reduce slab shifting
Built for stability under vibration, starts/stops, and road movement
Engineered A-frame approach for demanding hauling environments
Container Bundle Stabilization Mechanism
Container Bundle Stabilization Mechanism
Best for:
Unloading stone bundles from shipping containers at your facility.
Key benefits:
Stabilizes bundles before off-loading to reduce sudden tip-over events
Supports a safer unloading sequence from container to staging
Helps reduce severe incident risk during receiving and first movement

Safety Solutions by Workflow Stage
Choose where risk shows up in your operation, then jump to the systems built for that stage.
Warehouse & Yard Storage
Overhead Universal RockLock™
Everyday staging and repositioning can trigger over-center tipping risk if slabs aren’t stabilized consistently.
Transport & Delivery
Overhead Universal RockLock™
Vibration, shifting, and sudden stops can turn routine hauling into a tip-over event without the right system.
Container Unloading & Receiving
Overhead Universal RockLock™
Bundles can shift inside the container. The first movement during unloading is often when tipping risk spikes.

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
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

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.
Survivor crushed by 10,000 lb slab: 110 titanium screws hold his face together.

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.
