Overview

The Perko 1230DP0CHR is a pair of 4 inch straight chocks in chrome plated zinc alloy for leading dock and mooring lines at the deck edge. Each chock is 7/8 inch wide, takes rope up to 3/4 inch, and uses #8 mounting screws.

This is a straightforward piece of deck hardware for boats that need a clean line lead without taking up much space. The straight profile works well where the rope path is already direct and you want the line to stay controlled as it passes over the gunwale or deck edge.

Key features

• Sold as a pair for matching line leads on both sides or at two mooring points
• 4 inch overall length with a 7/8 inch width
• Fits rope up to 3/4 inch in diameter
• Chrome plated zinc alloy construction
• Mounts with #8 screws

Compatibility and fit

The main fit check is line size and mounting space. This chock is sized for rope up to 3/4 inch, and the 4 inch body gives you a quick reference when checking room on a cap rail, gunwale, or deck edge.

It suits boats that use conventional dock lines and want a compact fairlead point near a cleat or mooring location. It makes the most sense where the line runs in a straight lead rather than needing a wide turning angle through the hardware.

Installation and setup

Check the deck thickness and backing before installation, and match the fasteners to the structure of the mounting surface. The #8 screw size helps confirm the hardware requirement before drilling, especially when replacing an older chock or laying out a fresh set of mooring points.
