MATRIX® ST Truck Topper
Secure your gear. Skip the compromise.
The MATRIX® ST was built for truck owners who want secure, weather-protected storage without sacrificing accessibility or modern utility.
With its windowless design and Black River’s patent-pending opening system, the MATRIX® ST keeps valuable gear out of sight while giving you full, unrestricted access to your truck bed.
No crawling.
No digging.
No climbing halfway into your bed just to reach your tools or equipment.
Because your truck should work with you — not against you.
Built for Work. Ready for Anything.
From tools and recovery gear to hunting setups and camping equipment, the MATRIX® ST is designed to keep your gear protected, organized, and secure wherever the road takes you.
Its clean, windowless design adds privacy and peace of mind while giving your truck a more aggressive, modern look.
Perfect for:
- Work trucks
- Contractors
- Outdoor gear
- Hunting equipment
- Overland setups
- Recovery gear
- Everyday truck use
Pair it with the MATRIX® Lighting Kit for improved visibility when loading gear at night or before the sun comes up.
Full Bed Access Changes Everything.
Traditional toppers force you to crawl into your truck bed to reach gear buried in the front.
The MATRIX® ST changes that.
Its patent-pending opening system provides wide-open access to your truck bed, making it easier to:
- Reach tools and equipment
- Organize gear
- Load larger items
- Access the front of the bed
- Maximize usable storage space
Once you experience unrestricted bed access, it’s hard to go back.
Secure Storage Without the Hassle.
The MATRIX® ST features a dual adjustable slam-latch system with a single-point rear release designed to help protect your gear from theft, weather, dust, and debris.
No exposed handles.
No dangling locks.
No unnecessary complications.
Just clean, secure functionality built for real truck use.
Built to Handle Real Life.
Constructed from heavy-duty .063 automotive-grade aluminum with a durable matte black powder-coated finish, the MATRIX® ST is engineered to handle rough roads, changing weather, and everyday abuse.
Features include:
- Double-walled aluminum construction
- Premium perimeter weather seal
- OEM-quality gas struts

Modern Utility. Aggressive Style.
The MATRIX® ST combines rugged utility with a clean, modern profile that looks right at home on today’s trucks.
No oversized bulk.
No outdated fiberglass look.
No compromise between function and appearance.
Just secure storage, unrestricted access, and modern truck utility built the Black River way.
