Pile Hoop Roller Assemblies
Pile Hoop Roller Assemblies for Floating Docks
Designed to guide floating docks smoothly along pilings as water levels change, our Pile Hoop Roller Assemblies deliver strength, precision, and long-term reliability. Each unit is built from hot-dip galvanized steel with UHMW rollers for friction-free travel and dependable performance season after season.
What Is a Pile Hoop Roller Assembly?
A pile hoop roller assembly connects a floating dock to fixed pilings, allowing vertical dock movement with water-level changes while preventing twist or stress on the frame. The system uses a heavy-wall steel hoop anchored to the dock frame via two angle brackets, and a horizontal UHMW roller that presses against the piling to enable smooth motion.
How Pile Hoops Work on Floating Docks
Floating docks rise and fall with the water, but pilings remain fixed. The roller assembly forms the connection point between them—sliding up and down the piling as the dock moves. This prevents frame distortion and keeps your dock aligned under heavy load or wave action.
- Prevents structural stress — eliminates binding between dock sections.
- Ensures alignment — keeps docks parallel to pilings.
- Extends dock life — reduces torque and fatigue on fasteners.
- Improves safety — provides predictable, stable movement.
Hot-Dip Galvanized Steel Construction
Each Dock Hardware roller assembly is fabricated from 1-1/2″ Schedule 40 steel pipe and 1/4″ thick mounting plates, then hot-dip galvanized to coat every surface for maximum corrosion protection. UHMW rollers ensure smooth, low-friction operation and long service life in freshwater and brackish environments.

Frequently Asked Questions
What does a pile hoop roller assembly do?
It connects a floating dock to fixed pilings, allowing the dock to rise and fall with water levels while the UHMW roller provides smooth motion and prevents binding.
Can galvanized roller assemblies be used in brackish water?
Yes. Hot-dip galvanized coatings perform very well in freshwater and brackish environments with minimal maintenance.
How often should the rollers be inspected?
Inspect at least once per season to confirm the rollers spin freely and all fasteners remain tight. UHMW rollers are long-lasting and require little upkeep.
Are Dock Hardware roller assemblies made in the USA?
Yes — engineered, welded, and galvanized at our Rochester NY facility for consistent quality and fit.
