Stainless steel recessed lyre latch d. 12 – code: 01.081.12 – Osculati

Recessed stainless steel lyre shackle d. 12 Osculati (code 01.081.12)

The toggle latch with recessed pin is a hardware component designed for reliable connections in the nautical field, particularly in configurations related to anchoring. This Osculati version, identified by code 01.081.12, is made of AISI 316 stainless steel and adopts a tightening with Allen key cut, practical solution when a cleaner and less protruding profile compared to traditional pins is desired.

The “lyre” shape and the recessed pin are designed to facilitate the sliding and insertion of the anchor into bow rollers, helping to reduce the risk of the anchor snagging or “getting stuck” during maneuvers.

Features and construction details

Material: stainless steel AISI 316

The shackle is made of AISI 316 stainless steel, a typical choice for marine and onboard applications where hardware suitable for outdoor environments and exposure to weather elements is required. The material is consistent with use on deck and in areas near the bow, where salt spray and humidity are frequent conditions.

Recessed pin with Allen key tightening

The recessed pin with Allen key cut is designed to limit protrusions and snag points. In many installations, this detail helps maintain a tidier footprint and better manage passages near rollers, chain guides, and bow rollers, where a protruding pin can interfere with sliding.

“Lyre” geometry for anchoring connections

The lyre shape is commonly used to connect anchor and chain (or joining accessories) when a shackle body is needed that offers a useful opening and geometry suitable for working with anchoring components. In this version, the design is aimed at allowing the anchor to fit into the bow rollers without getting stuck, as indicated in the manufacturer's description.

Available sizes (variant d. 12)

This sheet refers to the variant d. 12 (also indicated as Ø 12), with the following measurements reported in the available data:

• Ø: 12
• A: 25
• B: 44

Note: The measurements are reported according to the manufacturer's nomenclature (Ø, A, B). For the correct choice, it is advisable to compare them with the dimensions of your bow roller and the elements to be connected (anchor, chain, or accessories).

Typical onboard applications

This stainless steel lyre shackle with recessed pin is suitable for uses where nautical hardware a compact connection suitable for bow maneuvers is desired. In particular, it is used in:

• Anchor connection in configurations where the anchor must fit back and slide correctly on the bow roller.
• Bow fittings with rollers and rollers, where a cleaner pin profile can help reduce interference.
• Mooring maintenance and refitting of anchoring systems, when replacing worn or no longer suitable components.

Being a connecting component, the choice should always be made based on the geometry of the anchor, the bow roller, and other present elements (for example, any joints or connections), favoring the absence of unwanted contact points during anchor raising and lowering.

Practical advantages

Neater profile and fewer snag points

The recessed pin reduces protrusions compared to solutions with a traditional nut or pin. This can be useful at the bow, where ropes, chains, and metal components work in often confined spaces.

Facilitates anchor insertion into the bow roller

The product description highlights that these shackles allow the anchor to slip into the bow rollers without jamming. In practice, the combination of lyre shape and recessed pin is designed to promote sliding and reduce situations where the anchor gets stuck or turns sideways during retraction.

Material suitable for the marine environment

The use of AISI 316 is a plus for those seeking hardware consistent with marine use and typical exposure in bow areas. It is a common choice when uniformity of materials and good long-term resistance in onboard conditions are desired.

Usage and operational notes

Size selection and clearance check

Before installation, verify that the measurement Ø 12 and the dimensions A 25 and B 44 are compatible with:

• the anchor eye or the intended connecting element;
• the chain or accessory to which it connects;
• the available spaces on the bow roller and the roller.

In case of doubt, it is preferable to physically compare the dimensions or refer to the configuration already present onboard, especially if the goal is to improve the anchor's sliding on the bow roller.

Hex key tightening

The pin with Allen key cut requires the use of the appropriate key. During assembly, make sure the pin is properly screwed in and that the shackle works in the correct position relative to the connected components, avoiding twists or abnormal contacts with the bow fitting.

Periodic checks

As with all anchoring hardware, it is good practice to perform regular checks: verify the general condition of the shackle, the absence of deformations, and the correct closure of the pin, especially after prolonged use or under demanding conditions.
