Overview

The Attwood Marine 11575-3 is a stainless steel mooring fender lock kit that gives you a quick way to hang, remove, or reposition fenders without untying the line each time. It accepts fender lines up to 1/2 inch in diameter and uses a flush-mount lock with removable keys, so you keep the line attached to the key and secure it at the boat only when needed.

This kit is set up for two fenders and suits boats that move lines often at the dock, fuel pier, or lock wall. The flush-mount receiver keeps the installed plate low on the surface, which helps reduce snag points along the gunwale while still keeping a dedicated attachment point ready for docking.

Key features

• Accepts fender line up to 1/2 inch diameter
• Stainless steel construction for the mounting plates and keys
• Flush-mount receiver leaves a low-profile plate on the boat
• Twist-lock style setup lets you move or remove fenders without retying the line
• Each receiver mounts with two #10 fasteners
• Pair configuration supports two separate fender positions

Installation and fit

Mounting is straightforward when you have a solid section of gunwale, cap rail, or another flat surface where a flush plate makes sense. Before drilling, it is worth checking clearance under the mounting area and confirming that your fender line stays within the 1/2 inch limit so the key seats and releases as intended.

This type of hardware is a good match for boats that dock frequently and need fast fender changes from port to starboard or between different tie-up points. It also works well where side-deck access matters and loose fender lines can get in the way.
