Perko 0330 Round Locker Ventilator, #6 R.H. Screw

Overview

The Perko 0330 is a round locker ventilator for adding passive airflow to enclosed storage areas, cabinets, and small compartments on board. It is a simple trim-mounted vent with no wiring, hose connection, or network integration, which makes it useful where a locker needs basic air movement without adding another powered component.

The range is offered in 2-1/2-inch and 3-1/4-inch outside diameters, with polished stainless steel and chrome plated brass finish options. Each size uses #6 R.H. screws, so it is a practical fit for light-duty mounting on locker doors, panels, and interior marine cabinetry where the cutout and surrounding surface match the selected size.

Key features

• Round locker ventilator for passive airflow in enclosed storage spaces, small cabinets, and similar interior boat compartments.
• Available in 2-1/2-inch and 3-1/4-inch outside diameter sizes for matching the vent opening and surrounding panel space.
• Finish options include polished stainless steel and chrome plated brass to suit different locker hardware and trim styles.
• Uses #6 R.H. screws, giving installers a clear fastening reference before drilling or replacing an existing vent.
• No electrical connection is required, so installation is limited to sizing, fastening, and confirming the mounting surface is suitable.

Variants

This Perko locker ventilator is offered in four configurations that change by outside diameter and finish.

The size changes the face diameter of the vent, while the finish changes the visible appearance on the locker or cabinet surface. The round vent format and #6 R.H. screw requirement remain consistent across the listed configurations.

• 0330DP1STS: 2-1/2-inch size with stainless steel finish. This smaller stainless version works well where panel space is limited or where the surrounding hardware already uses stainless trim.
• 0330DP2STS: 3-1/4-inch size with stainless steel finish. This larger stainless version gives the vent more visual presence and suits larger locker faces or replacement openings in that size.
• 0330DP1CHR: 2-1/2-inch size with chrome finish. This compact chrome version matches bright chrome hardware and is useful when replacing a same-size vent in an interior locker panel.
• 0330DP2CHR: 3-1/4-inch size with chrome finish. This larger chrome version suits panels that need the 3-1/4-inch face size while keeping a polished chrome look.

Installation and fit

Before installation, confirm the available panel space, the required opening, and the existing screw pattern if this is a replacement. The stated outside diameter is the visible face size, so the selected variant should be checked against both the cutout area and the trim coverage needed around it.

For lockers used to store lines, fenders, cleaning gear, or damp equipment, this style of vent helps keep air moving through the compartment. It is best suited to interior or protected locker locations rather than applications that need forced ventilation, electrical fans, or sealed exterior airflow management.

Materials and finish selection

Stainless steel is the current finish for the 0330 series and is a good match for boats using stainless interior and deck hardware. Chrome plated brass versions provide a bright traditional look and may be used where the vessel already has chrome trim or where the owner is matching an existing installation.
