Whitecap Locking Nylon Access Plug T-handle — 3" Cover for 2-1/2" Cut-Out, Corrosion-Resistant

The Whitecap T 3226BC is a locking nylon T-handle access plug designed to secure 3" openings with a 2-1/2" cut-out and adjustable surface depth for durable marine and industrial use.

Engineered for boat builders, repair professionals, and hobbyists who need a robust, low-profile access solution, the T 3226BC combines a corrosion-resistant nylon body with a keyed locking T-handle and an included fastener. Its compact 3" overall diameter and shallow surface depth range make it ideal where space is tight and a watertight, tamper-resistant access point is required. The T-handle locks down to prevent accidental opening while the fastener provided simplifies installation.

How does the locking T-handle improve security and convenience?

The T-handle locks into place to resist unintentional opening and offers extra leverage when you need to turn or remove the plug. The keyed lock prevents casual tampering while the T-shape provides comfortable grip even when wet or greasy.

• Locking mechanism with included key for controlled access
• T-handle profile for strong grip and torque
• Nylon construction resists corrosion and stays lightweight
• Fastener included to streamline installation

What sizes and panel depths does this plug fit?

This model fits a 2-1/2" cut-out and covers a 3" overall opening, making it suitable for common access panel applications. The surface depth acceptance ranges from 1/8" up to 3/4", allowing it to clamp down on thin skins or slightly thicker panels without extra hardware.

• Cut-out requirement: 2-1/2" (standard drilled opening)
• Overall cover diameter: 3" for neat flush appearance
• Surface depth compatibility: 1/8"–3/4" for versatile mounting
• Includes fastener sized for secure clamping across depth range

Is it suitable for marine, RV, and industrial installations?

Yes—the nylon body resists saltwater corrosion, and the locking T-handle reduces unwanted access in exposed environments. While not a pressure-sealing hatch, its design provides reliable closure and protection for wiring, valves, and small access cavities where a sturdy, tamper-resistant plug is needed.

• Corrosion-resistant nylon for marine and outdoor use
• Low-profile cover for crowded panels and consoles
• Locking feature deters unauthorized opening
• Quick install with the supplied fastener

Who is this for? The Whitecap T 3226BC is aimed at boat owners, RV technicians, electricians, and maintenance teams seeking a compact, lockable access plug that’s easy to install and corrosion-resistant. Pick it when you want a tidy flush cover with a secure T-handle for occasional access to compartments, hose fittings, or control areas—especially where exposure to moisture and rough handling are concerns.
