Product Description

For decades, NPL has manufactured some of the largest hardshell navigational buoys which have been utilized by coast guards throughout the world. Drawing upon that experience and knowledge we have created a line of polyethylene buoys that offer high visibility, durable materials, and superior connections for securement. Our mooring buoys are designed to meet federal requirements and reduce deployment costs. They come with a galvanized rod or hawser style chain attachment option.

Highest quality UV stabilized, seamless one-piece construction with uniform wall thickness:
Ultra High Molecular Weight (UHMW) Plastic Wear Collar:
Direct connection to the mooring chain:
Refined EPS foaming process with over 20 years of experience:
Pre installed owner information label & clear protective overlaminate
