Heavy-Duty Stainless Latch 98×28 mm (AISI316) – Padlock Loop & Built-in Lock Versions

This reinforced stainless latch (also known as a heavy-duty hasp or locking mechanism) is designed to ensure that important hatches and compartments on your boat stay securely closed, even in rough conditions. Made from high-strength AISI316 stainless steel, the latch is weather-resistant and will not corrode even under constant saltwater exposure. Its 98×28 mm size and heavy-duty construction mean it can withstand strong pull forces or impacts (for instance, from sudden slamming or tampering attempts) without bending or breaking.

The padlock-ready version (01005-1) features a sturdy eye/loop intended for inserting a padlock. This gives you flexibility – you can secure the latch with a padlock of your choice, or leave it latched without a lock when quick access is more important than locking. This version is favored for hatches that are opened frequently or when you want to use a single padlock to secure multiple compartments (for crew convenience). The loop is reinforced to resist being pried open or cut, ensuring that security is not compromised when a padlock is used.

The built-in lock version (01005-2) incorporates an integrated locking mechanism (barrel lock) and comes with a set of keys. This option provides quick and convenient locking – just turn the key to lock or unlock – without needing a separate padlock. The lock cylinder is constructed with corrosion-resistant materials and is shielded against water intrusion, ensuring smooth operation and longevity. This version is ideal for securing cabin doors, electronics lockers, or engine bay hatches where enhanced security is important. For example, it allows you to lock your cabin or important equipment compartments when you leave the boat unattended, acting as a deterrent to theft as well as keeping the hatch firmly closed.

Both versions have a low-profile design: when the latch is closed, it sits nearly flush, with no sharp edges sticking up that could snag ropes or cause injury. Installation is straightforward – the base has pre-drilled holes to accommodate screws or bolts (use stainless hardware for best results), and the entire assembly can be mounted on a variety of surfaces (fiberglass, wood, metal). It’s recommended to install the latch on a flat surface so that the hasp and loop align correctly, ensuring smooth engagement and disengagement.

• Use of Padlock Version: Suitable for lazarette hatches, equipment covers, and compartments that need to stay shut securely but aren’t always locked – e.g., a fishing tackle box, a hatch covering life jackets, or rope lockers. You have the option to add a padlock when security is needed (for instance, when the boat is unattended at dock or mooring). This version is popular on boats of all sizes as a general-purpose strong latch for day-to-day cruising where quick access is needed but you still want the ability to lock up when necessary.
• Use of Keyed Version: Ideal for cabin doors, engine room hatches, or lockers holding valuable equipment where access control is required. For example, on an 8–10 m sailboat, you might install this locking latch on the companionway hatch or cockpit lazarette to secure personal belongings when you leave the boat. The built-in lock provides a higher level of protection against unauthorized entry or accidental opening. In both versions, the stout latch body keeps the hatch tightly closed, preventing it from vibrating open and helping to maintain a watertight seal (especially if the hatch has a gasket).
• Maintenance Tip: Rinse the latch with fresh water periodically to remove salt and grit, especially around the moving parts. For the keyed version, apply a drop of lubricant into the lock cylinder a few times a year to ensure smooth key operation (use a marine lock lubricant or silicone spray). By maintaining it properly, this reinforced latch will give you trouble-free service for many years, keeping your boat’s compartments secure and protected.
