K&R Manufacturing Dock Corners/Bumpers/Profiles

K&R Manufacturing Dock Corners, Bumpers & Profiles: Serious Protection for Serious Docks

When a boat meets a dock, the difference between a scratch and a gouge often comes down to what's protecting the edge. K&R Manufacturing has built a reputation as a trusted name among marina operators and dock builders alike, and their dock corners, bumpers, and profiles are a clear example of why. Engineered for the demanding marine environment, K&R's dock protection lineup combines smart material science with practical installation design to guard both your vessel and your dock investment.

Marine-Grade Materials Built to Last

K&R Manufacturing takes a material-first approach to dock protection. Their vinyl edging products — including edge profiles and corner bumpers — are constructed from a flexible, marine-grade PVC compound that is extruded for consistency and dimensional accuracy. All vinyl edging is extruded from a marine-grade flexible PVC compound, with UV and elements protection added to maximize the material's lifespan. This means the profiles hold up against sun, saltwater, and repeated impacts without cracking, fading, or becoming brittle over time.

For flat bumper applications, K&R turns to a different material entirely. Their flat cushion bumpers are constructed with high molecular weight, high-density polyethylene (HDPE) that is UV-stabilized for added toughness and durability. This heavy-duty material resists deformation under load and won't mar or mark boat hulls — a critical feature when protecting everything from aluminum fishing boats to fiberglass cruisers.

Multi-Channel Profile Design for Maximum Absorption

One of the standout engineering choices in K&R's vinyl profile lineup is their channel construction. The sturdy three-channel design features three air-cushioned, impact-absorbing chambers, with chamber sizing and wall thickness engineered to allow profiles to fit a wide range of applications. This isn't just about padding — those air chambers act as progressive buffers, dissipating impact energy before it can transfer to the dock frame or boat hull.

Flexible Mounting for Any Dock Layout

K&R's bumper and profile products are designed with real-world dock configurations in mind. Their flat bumpers can be positioned both horizontally and vertically, accommodating a variety of applications and attaching easily in different scenarios. Vertical positioning protects dock posts, while horizontal positioning guards along the dock edge — protecting both the boat and the dock structure itself. Some flat bumper models even feature a notch specifically designed to hug square posts or round pipe, ensuring a snug, rattle-free fit.

A Product Line Built for Marinas and Dock Builders

K&R is a preferred supplier to marinas and dock builders, and the company is family-owned and operated since the 1980s, currently running under third-generation ownership. That long institutional knowledge shows in the breadth of their dock protection catalog, which spans urethane foam corner bumpers, vinyl HD bumper profiles like the flagship KR5001, super cushion post bumpers in multiple lengths, and corner-specific solutions for protecting the most vulnerable points of any dock structure. Available in black and white, their bumpers will not mar or mark and provide protection for all sizes of vessels and docks.

Whether you're outfitting a private lakefront dock or a full commercial marina, K&R Manufacturing's dock corners, bumpers, and profiles deliver the material quality, design intelligence, and installation flexibility that serious dock owners depend on season after season.
