T-H Marine Anchor Handle Lock for Anchor Lockers — Locking, Waterproof stainless stem & gasket

The T-H Marine ALC-1-DP Anchor Handle Lock is a compact, waterproof lock-and-handle assembly that secures anchor compartments and fits aluminum, fiberglass and carpeted lids up to 3/4" thick.

Designed for marine hatches and anchor lockers where a low-profile, durable locking handle is needed, this model combines a two-finger ergonomic grip with corrosion-resistant components and seals to keep water and debris out. It installs through a 2-3/8" to 2-1/2" cutout and uses a single hex nut for straightforward mounting, making it a practical replacement or upgrade for many small boat lids and compartments.

How does this lock handle different lid materials?

The ALC-1-DP includes mounting features and a gasket to adapt to common marine lid surfaces. For carpeted lids it uses a toothed, Double-D shaped mount that bites into the material; for smooth aluminum or fiberglass it supplies a compressible gasket to form a reliable surface seal.

• Toothed Double-D mount for secure fit on carpeted lids
• Compressible gasket for smooth fiberglass or aluminum
• Fits lids up to 3/4" thickness without extra parts
• Installs in 2-3/8"–2-1/2" hole sizes

Will it resist water and corrosion in a marine environment?

Yes — the design centers on sealing and longevity rather than decorative trim. A molded "O" ring provides a waterproof barrier around the stem while the stem itself is stainless steel to resist rust and electrochemical wear in saltwater conditions.

• Waterproof "O" ring for stem sealing
• Stainless steel stem for corrosion resistance
• Gasket reduces water intrusion at the lid surface

How easy is installation and everyday operation?

Installation is intended to be simple: the lock fits the specified hole diameter and secures with a single hex nut, so you can swap an old unit or retrofit a new lid quickly. Operation uses a two-finger handle for positive grip and intuitive anchor release or locking motion.

• Installs into standard 2-3/8"–2-1/2" hole cutouts
• Single hex nut mounting—minimal hardware required
• Two-finger handle offers secure, repeatable operation

What maintenance and compatibility should I plan for?

Maintenance is low but recommended: check the O-ring and gasket periodically for wear, and rinse exposed hardware with fresh water after heavy salt exposure. The ALC-1-DP is sized to match common locker cutouts and works well as a direct replacement for similar T-H Marine and aftermarket handles.

• Inspect O-ring and gasket annually or after rough use
• Rinse and dry after saltwater exposure to extend life
• Compatible with many standard anchor locker cutouts and lids

Who is this for: boat owners, small-cruiser captains, and marine maintenance professionals looking for a compact, seaworthy anchor handle lock that balances ease of installation, reliable waterproofing, and materials chosen to resist marine corrosion. It's a practical option when you need a rugged replacement handle for anchor lockers, storage hatches, or custom lid projects on vessels with 2-3/8" to 2-1/2" holes.
