WhamGuard Rotating Bumpers.  Boat Dock Rollers that Work!

WhamGuard is dedicated to providing boat and dock protection solutions.  WhamGuard Rotating Bumpers help boat owners and marina owners protect themselves, their boats and docks from injury and damage.  Rotating Bumpers are boat dock rollers that are designed to actually roll and guide a boat in or out of a boat slip, preventing damage to boats and boat docks.


Patent pending WhamGuard Rotating Bumpers are a 13.5″ x 13.5″ sphere that attaches to the dock post with a bushing in the center.  No drilling to the dock structure is required since the bushing fits snug on posts measuring 2″ round, 2″ square and 2.5″ square.  Before ordering, you will want to know the dimensions of your dock post.

WhamGuard Offers Unique Solution

WhamGuard Rotating Bumpers are a patent pending, unique boat dock roller option for boats entering or exiting a boat slip. The bumpers are uniquely designed to absorb impacts and guide a boater into a slip.  The rotating bumper prevents or minimizes damage to boats and dock structures. Other boat dock rollers often don’t work as advertised.  Sometimes they roll, but most of the time they don’t.  WhamGuard Rotating Bumpers solves this problem by attaching to the post with a patent pending bushing design.  The design allows for easy attachment without having to drill or compromise the integrity of the steel dock post.

Your Dock Should be a Stress Free Zone!

Often the most stressful time for boaters is entering or exiting a boat dock slip. Waters can be rough. Docking a boat can be dangerous, and damage significant, when docking in rough water. Also, marinas squeeze as many slips into an area as possible, leaving little room for error when boaters launch or dock with other boats and slips in close proximity. Even calm water can be a challenge. Boats don’t have brakes and the steering is not very responsive, especially at low speeds.

WhamGuard Rotating Bumpers are different than other bumpers or boat dock rollers.  The design, material construction, color options, price, and attachments are patent pending and truly unique.  The WhamGuard boat dock roller is easily retro-fitted to existing dock structures. Other boat dock roller manufacturers are limited by size, weight, capabilities and cost. WhamGuard Rotating Boat & Dock Bumpers are constructed of lightweight, but strong high-density polyethylene material that has the highest UV rating.

WhamGuard Rotating Bumpers are boat dock rollers that are easy to install and look great while protecting your boat and dock.  Make your dock a stress free zone.  Don’t slam hard.  Get WhamGuard!
