RockLock™: The Adjustable Arm Safety System That’s Changing the Industry
Handle and Move Massive Stone Slabs—Without the Massive Risk
The RockLock™ TAF 30 is the industry’s strongest safety frame for transporting stone slabs on flatbed trucks. Engineered to secure up to 30 slabs with zero tipping, shifting, or guesswork, it delivers four layers of built-in protection to safeguard your crew and your cargo:
Undermount Bolt-On System – Heavy-duty mounting bar bolts through the truck bed, locking the frame in place with zero movement.
RockLock™ Adjustable Arms – Patented locking arms secure each slab individually to prevent tipping during loading, unloading, or transit.
Barrier Poles – Upright containment poles prevent lateral shifting and provide added slab support from both sides.
Collision Barrier Bar – A front-facing steel bar shields the truck cab by stopping slabs from entering the driver’s space in the event of a sudden stop or crash.
This isn’t just a rack—it’s a fully integrated slab transport safety system trusted by industry professionals who refuse to compromise on safety.
Transporting Slabs on Flatbeds? One Mistake Can Cost Everything.
Regularly, fabricators and distributors load full-size slabs onto flatbeds with ratchet straps, wooden A-frames, and crossed fingers. The result?
Workers crushed while loading and unloading
Tipped slabs on the interstate
Broken and shattered inventory
Large spills causing dangerous messes and expensive cleanups
OSHA violations, fines, and lawsuits
Semi-truck granite spill on I-24 causes massive delays.
One incident can shut down your operation, destroy your margins, or worse—take a life.

➡️ As soon as the slab is seated, the arm drops to secure it
Removing a Slab:
➡️ The slab is lifted by forklift or crane
➡️ Once clear, the locking arm immediately protects remaining slabs
Result:
➡️ At no time is a slab unsecured.
