Stair Ninja™ — Low-Profile Corner Protection for Stone Transport
The Stair Ninja™ is a corner protection tool engineered specifically for stone installers who need to move slabs, countertops, and other stone material through stairs, low door frames, and tight jobsite conditions. Sold as a set of two, it clamps directly onto material edges up to 4 3/4" thick, shielding vulnerable corners from damage during transport where carts and dollies alone may fall short. Each unit supports up to 600 lbs, giving the set a combined load capacity of 1,200 lbs. The Stair Ninja™ can be used independently or in conjunction with Omni Cubed carts and dollies for added protection during challenging moves.

Unlike standard edge guards or foam padding, the Stair Ninja™ is purpose-built for active transport scenarios — clamping securely to material edges rather than relying on adhesives or loose placement. Its low-profile design allows it to pass through tight clearances that would otherwise make corner protection impractical, and its compatibility with Omni Cubed transport equipment makes it a natural addition to an existing material-handling system.
Key Features & Benefits
Corner Clamping Design
The Stair Ninja™ clamps directly onto material edges up to 4 3/4" thick, keeping it securely in place during movement. This eliminates the risk of protection slipping off mid-transport on stairs or through doorways.
High Load Capacity
Each unit is rated to 600 lbs, with the set supporting a combined 1,200 lbs. This capacity is sufficient for heavy stone slabs and countertops commonly handled on residential and commercial jobsites.
Low-Profile Form Factor
The low-profile construction allows the tool to pass through low door frames and tight clearances without adding significant bulk to the load. This is critical when navigating interior spaces where overhead and lateral clearance is limited.
Compatible with Omni Cubed Transport Equipment
The Stair Ninja™ is designed to work alongside Omni Cubed carts and dollies, allowing installers to integrate corner protection into their existing material-handling workflow. Using both together provides comprehensive protection during the most demanding transport conditions.
Sold as a Set
Packaged as a set of two units, the Stair Ninja™ provides protection for both corners of a slab edge simultaneously. This ensures balanced support and reduces the risk of uneven stress on the material during a move.
Common Applications
Stair Transport
Protects stone corners when carrying slabs or countertops up or down stairs, where edges are most exposed to impact against steps and railings.
Low Door Frame Navigation
Shields material corners when moving through low-clearance doorways where the risk of corner strikes is elevated.
Tight Jobsite Conditions
Provides corner protection in confined interior spaces where maneuvering room is limited and the chance of incidental contact with walls or fixtures is high.
Use with Carts and Dollies
Pairs with Omni Cubed transport carts and dollies to add corner-level protection during wheeled material moves across a jobsite.
Compatible Materials
- Natural stone slabs (granite, marble, quartzite, etc.)
- Engineered stone and quartz countertops
- Stone tile and large-format panels
- Other rigid slab materials up to 4 3/4" thick
