Pile Rollers and Pile Retainer Rings:
Pile rollers were developed in the 1960’s as an effective way of holding a floating structure securely to a guide piling. Prior to pile rollers, the industry was using either a metal pile ring or wood rub blocks for this purpose. Both of these methods have their place in some types of construction and in relatively quiet waters. With the increased use of concrete pilings instead of wooden pilings, and with many marinas being built in locations with high tidal changes and current flows, it was necessary to find a better way to connect the dock structure to the pilings.

Pile Ring Retainer - Breakaway
This “break away” type pile retainer ring was designed for applications where the pile ring has to be added after construction of the dock system, and where a tidal situation makes it impossible to physically place the ring over the pile. The strength and holding power of this ring
are equally as good as our standard pile retainer ring.

Pile Ring Retainer - Standard
When bolted to the outside face of a dock, these pile retainer rings are the most common method of holding a dock to a piling.

Pile Roller Assembly
In 1976, Henderson Marine developed a superior pile roller utilizing a revolutionary new material called UHMW (Ultra High Molecular Weight) plastic as the roller part of the assembly, a solid stainless steel axle and a choice of two mounting brackets. This pile roller assembly has been installed in many marinas and boat harbors, and has performed exceedingly well on every installation without exception. |

Pile Roller Axle
This axle is made from a solid piece of stainless steel rod (alloy T304). It is held in place on the bracket with galvanized or stainless steel washers and stainless steel cotter pins on each end. As the roller is totally self- lubricating, it moves on the axle easily without binding or hanging up. The axle is never required to move or turn. |

Pile Roller Mounting Bracket
This bracket is unique to the marina industry in that it was designed by Henderson Marine to address the problems of the old style bracket designed in the 1950’s. This improved bracket was professionally designed and engineered to withstand maximum loading in all directions. It is cast from high strength ductile iron, so it is 50% stronger than the conventional welded bracket. Besides being stronger and better looking, we added an adjustable feature and placed the mounting holes so that the complete unit can be quickly installed without disassembly. The unit is hot dipped galvanized. |

Pile Roller - Ultra High Molecular Weight (UHMW)
This roller is made of a revolutionary “Ultra High Molecular Weight” plastic that is self lubricating, unaffected by marine environment, and next to impossible to wear out. On-the-job wear test and engineering data shows that this material wears five times better than any rubber or polyolefin materials on the market. |
