Wichard MXEvo Friction Block Captive Pin, 10mm, Max rope 14mm

6,000kg Breaking Load. 2,640kg Working Load. Only 222g. Serious strength without unnecessary weight.

The Wichard MXEvo #11605 is designed for sailors who need to handle substantial loads while keeping their rigging hardware compact, lightweight and simple.

This 10mm MXEvo friction block accommodates ropes up to 14mm and combines an exceptionally strong monobloc design with a captive pin that stays attached to the block during installation and handling.

With dimensions of just 77 x 44mm, it achieves a remarkable 2,640kg nautical Working Load and 6,000kg Breaking Load at a weight of only 222g.

MXEvo – Wichard’s New Generation Friction Block

The MXEvo represents Wichard’s new generation of one-piece friction blocks.

Unlike a traditional pulley block with a rotating sheave and multiple mechanical components, the MXEvo uses a monobloc design without mechanical parts.

The rope runs over a specially designed track, allowing Wichard to create a block that is:

• Extremely compact
• Lightweight
• Strong
• Simple to install
• Designed for improved reliability
• Optimized for high-load applications

This makes the MXEvo particularly attractive for modern performance sailing, where unnecessary weight and mechanical complexity are best avoided.

Built for Heavy Loads

The #11605 is specifically designed for heavy-load applications.

Wichard specifies:

Nautical Working Load: 2,640kg

Breaking Load: 6,000kg

The manufacturer identifies the 2,640kg Working Load as the rating for nautical applications.

For a friction block measuring only 77mm long and weighing 222g, these figures demonstrate impressive mechanical performance.

10mm Captive Pin

The #11605 features a:

Ø10mm Captive Pin

The captive pin is an important practical advantage when installing or reconfiguring the block on board.

A leash keeps the pin connected to the MXEvo while the block is being opened, handled and closed. This greatly reduces the possibility of accidentally losing the pin while working on deck or around the rig.

The pin itself is forged from high-resistance HR 17-4 PH stainless steel, providing high mechanical strength at this critical connection point.

For Ropes up to 14mm

The Wichard #11605 is designed for:

Maximum Rope Diameter: 14mm

This makes it the largest captive-pin version in the current three-size MXEvo range, above the 6mm and 8mm pin models.

The block’s track has been carefully designed to manage the rope correctly while helping to limit rope wear.

Integrated fins also help keep the rope correctly positioned on the track.

Only 222g

High load capacity does not necessarily require bulky hardware.

The MXEvo #11605 weighs just:

222g

Yet it provides:

Working Load: 2,640kg
Breaking Load: 6,000kg

This exceptional strength-to-weight ratio makes the MXEvo particularly attractive for performance and racing sailing, where reducing weight in the rig and running rigging can be highly valuable.

Monobloc Construction – Simple & Reliable

One of the key design characteristics of the MXEvo is its one-piece / monobloc architecture.

There are no conventional moving mechanical parts inside the block. Instead, the rope follows the specially shaped friction track.

Wichard specifically highlights this mechanical simplicity as a way to achieve better reliability, while also optimizing the overall dimensions and weight of the block.

For the right application, the result is a very compact alternative to a conventional pulley block.

Rope-Retaining Fins

The MXEvo incorporates specially designed fins that help keep the rope on its track.

This is particularly useful during installation, handling and changes in line tension.

By helping maintain correct rope positioning, the fins contribute to the practical, user-friendly design of the MXEvo.

Designed to Limit Rope Wear

High-load systems can place considerable stress on running rigging.

Wichard has therefore designed the MXEvo’s track to help limit rope wear.

This is especially important when using modern high-performance ropes in demanding sailing applications, where protecting the line is just as important as selecting strong hardware.

Integrated Becket Function

The Wichard MXEvo #11605 also features an integrated:

Becket Function

This allows the friction block to be incorporated into suitable tackle / purchase systems, increasing its versatility beyond simply redirecting a line.

Wichard specifically identifies the becket function as a feature for creating tackles.

For performance sailors looking to build compact high-load purchase systems with minimal hardware, this is a particularly useful feature.

Ideal for 2:1 Halyard Systems

Wichard specifically lists 2:1 halyard purchase systems among the intended applications for the MXEvo.

These include:

• Mainsail halyard
• Spinnaker halyard
• Gennaker halyard

A correctly configured 2:1 system can help manage significant loads while providing an efficient rigging solution for modern performance yachts.

Flying Sail Furler Terminals

Another application specifically identified by Wichard is:

Flying Sail Furler Terminals

The MXEvo can be used in suitable systems for tensioning from the top or from the bottom.

This makes the #11605 particularly relevant to modern flying sails such as gennakers and other compatible sail configurations where high loads and minimum hardware weight are important.

Easy Opening & Rope Installation

High-performance hardware should also be practical to work with.

The MXEvo has been designed around:

Easy opening → Easy rope installation → Easy closing

The captive-pin system makes handling even more convenient because the pin remains connected to the block by its leash when opened.

This is an important advantage when hardware needs to be installed or reconfigured quickly on board.

Premium Stainless-Steel Construction

The MXEvo #11605 combines two stainless-steel grades in its construction:

316L Stainless Steel

HR 17-4 PH Stainless Steel

The main technical information lists 316L stainless steel, while Wichard specifies that the captive pin is forged from high-resistance 17-4 PH stainless steel.

This combination provides the corrosion resistance expected from premium marine hardware together with exceptional mechanical strength at the pin.

Compact 77 x 44mm Dimensions

Despite being the largest captive-pin model in the MXEvo range, the #11605 remains impressively compact.

Length: 77mm

Width: 44mm

Weight: 222g

These compact dimensions are particularly valuable when installation space is limited or when reducing the overall size and weight of the rigging system is a priority.
