Kolpin Ratcheting Rhino Grip — Pair (Black), universal quick-release holders for 1–4" gear

Kolpin Ratcheting Rhino Grip (21540) is a pair of universal, quick-release holders that secure long gear up to 4" diameter on ATVs, UTVs, boats or any mountable surface.

Built to keep rifles, bows, fishing rods, shovels and other long implements safe and within reach, the Ratcheting Rhino Grip combines a cushioned rubber contact surface with a ratcheting arm and a rugged mounting base. Each grip pair supports medium-weight items with up to about 15 lbs of carrying strength and installs on tubular rails, square bars or flat surfaces for flexible placement. The quick-release button and indexed arm let you stow and retrieve gear fast, while the Kwik-Clip base adds rotational adjustability and easy removal when you need it.

How does the ratcheting system secure different tool sizes?

The ratcheting arm locks the grip at incremental positions so objects from about 1" to 4" in diameter are held firmly. The inlaid soft rubber cushions irregular shapes and reduces slippage under vibration.

• Indexed ratcheting arm for gradual tightening and positive lock
• Soft cross-pattern rubber to conform to round, flat, or tapered shafts
• Accommodates 1"–4" diameters — from small poles to larger fishing rods

Will these grips fit my ATV or boat rails?

The heavy-duty base accepts tubular and square rails between 5/8" and 2" diameter, and it also mounts to any flat surface that can be drilled for bolting. A four-corner bolting system and Kwik-Clip design make the assembly both robust and serviceable.

• Mounts to 5/8"–2" tubular or square bars without special adapters
• Flat-surface installation uses the included four-corner bolt pattern
• Kwik-Clip allows base rotation and quick removal of grips for repositioning

How fast can I access my gear in the field?

A one-handed quick-release button lets you open the grip instantly for rapid access, while the cushioned hold keeps items secure during transport. The mechanism is designed for frequent use so you can retrieve or stow gear without fumbling.

• Quick-release button for immediate opening with one hand
• Ratcheting index prevents accidental release while moving
• Durable nylon construction resists wear from repeated operation

What kinds of loads and conditions are these grips made for?

Rated for roughly 15 lbs of carrying strength per pair, these grips are optimized for medium-weight tools and sporting gear rather than extreme loads. Materials and design account for outdoor use on ATVs, UTVs, and boats where vibration and exposure can be factors.

• Approximately 15 lbs carrying capacity for medium-weight gear
• Heavy-duty nylon body with inlaid rubber grip texture for durability
• Works well in outdoor environments—mountable on vehicles and flat surfaces

Who is this for: The Kolpin Ratcheting Rhino Grip (21540) pair is aimed at outdoorsmen and professionals who need a reliable, fast-access way to carry rifles, bows, poles and tools on ATVs, UTVs, boats, trucks or storage racks. If you want a versatile holder that adapts to multiple shaft sizes, installs on common rail sizes or a flat deck, and releases quickly with one hand, these grips are a practical, long-lasting solution.
