Overview

The Perko 0960DP0CHR is a chrome-plated zinc alloy mortise latch set with an inside turn-button lock for boat cabin doors and interior compartments. It fits doors from 1" to 1-3/8" thick, with a 2-1/4" x 1-13/16" case and a 4-3/8" x 1-1/4" escutcheon, so it is worth checking the existing cutout and door thickness before ordering.

This latch is a practical replacement for interior marine doors where a low-profile mortise installation and simple privacy locking are needed, such as cabin entries, heads, berths, and passage doors. The reversible bevel helps during installation because the latch can be set up for different door swings without needing a separate left-hand or right-hand version.

Key features

• Chrome-plated zinc alloy construction for interior boat hardware applications where appearance and everyday wear matter.
• Turn-button lock allows privacy control from inside the cabin or compartment.
• Reversible bevel supports installation on doors with different swing directions.
• Fits door thicknesses from 1" to 1-3/8", a common range for many cabin and interior marine doors.
• Case dimensions are 2-1/4" x 1-13/16", with a 4-3/8" x 1-1/4" escutcheon for checking fit against the existing mortise pocket and trim footprint.
• Uses #6 screws, making fastener planning straightforward during replacement or refit work.

Installation and fit

Because this is a mortise latch, the door must have enough thickness and edge depth for the latch body. Before installation, compare the 2-1/4" x 1-13/16" case size and 4-3/8" x 1-1/4" escutcheon size with the current latch opening, especially on older boats where door hardware may have been modified over time.

The bevel can be reversed during installation, which helps match the latch to inward-opening or outward-opening doors. Use #6 screws suitable for the door material and mounting location, and check that the latch operates freely before final tightening so the knob, bevel, and strike alignment do not bind.

Use cases on board

This latch set is a good match for boat owners replacing worn cabin door hardware, updating interior trim, or restoring a simple privacy latch on a head or berth door. It is not an electrical or networked component, so fit comes down to door thickness, mortise dimensions, trim coverage, and door swing.
