KMH8 (15MM) INTERNAL LOCK
Internal lock KMH8. Working load up to 8T and mast thickness up to 15mm.
An internal lock is a hook integrated into the mast and dedicated to the sails in front of the mast (staysail, gennaker, codes,…). The KMH lock is particularly innovative and efficient. From the KMH5, the entire locking system is accessible under its cover (2 screws) and can then be removed without tools. Unlike many other locks, the sheave is not under tension once the sail is hooked. This innovation makes it possible to avoid the use of high-load strop and reduces the compression of the mast. For many of our competitors, access to mechanics is almost impossible at sea.
The internal hook is often preferred to the external hook on larger units for aesthetic reasons and usage patterns. A lock (internal or external) makes it possible to completely remove the tension in the halyard. The halyard no longer needs to be sized to hold the load, the halyard jammer is no longer useful, the lock removes the elasticity of the halyard which distorted the sail profiles. The mast compression decreases. KMH : Simple and aesthetic. Reliability above all !

– The hooking mechanism can be completely dismantled without tools and without having to dismantle the support. It is very easily accessible and is not inside the mast.
– Access to the mechanism by a cover in a customizable color (black as standard, yellow, red, carbon, etc,…)
– Ultra proven hooking technology. Same technology as our KFH hooks on board 70% of the boats in the last Vendée Globe.
– No additional hooking command. The halyard acts as a control
– Use of a small diameter halyard (weight savings & price)
– Ultra compact and light. Take the time to compare !
– Range from 2T (30ft sailboat) to 50T and more (Super Yachts)
– Easy installation. The support fits into its own mast cutout.
– Mast manufacturers who trust us only stock KMH brackets. The hooking cylinder which is the most expensive part of the system is ordered a few days before delivery and put in place in a few seconds.
– No strop to replace regularly
– Customizable cover color. Also available in wood finish.
– The rounded shape of the mobile part allows large hooking angles
– Large hooking surface : more reliability and lighter
– The use of a lock involves the use of a hoist system on the bridge to take up the tension.
– Using a lock, a 12mm halyard can be replaced with a pure 6mm Dyneema. We recommend using a rigger to increase the diameter of the line over the first few meters of the halyard if you want more comfort.
– We have designed our locks to be the lightest and most compact on the market. However, of course we know how to make them heavier and less compact if specific specifications require it.
– Unlike the KFH external swivel lock, the KMH does not have an integrated swivel. It is therefore necessary to connect a standard furling swivel to store a sail.
– Mark your halyard (whipping) to have a reference point and know when the mobile part of the hook will join the fixed part. The hooking will then be done within 5 centimeters.
– Release the tension of the anti torsion well for easy unhooking
– The KMH5, 8 and 10 hooks are available in 2 depths to adapt to different mast thicknesses
– Some manufacturers order the KMH without their support (stainless steel) to integrate the cylinder in a carbon housing made by them
– We also offer straight KMH for applications other than headsails (mainsail, tack, reef, etc, …)
