Duotone Uni.XT 2026
Item-no. 14220-7301 · Sizes: SDM 28, RDM 36, SDM 42 · Colors: C99 Random
UNI.XT – the most technically advanced and yet the most lightweight standard aluminium extension we have ever built. Now also built using SLS carbon technology to create the most lightweight extension in the world.
When it comes to standard extensions, everyone has probably experienced some nasty surprises at some point. They rarely fit with the rope alignment on the sail, most of them need high downhaul forces, and more often than not the mechanism for adjusting the height is extremely fiddly. Before designing the UNI.XT we analysed all of these issues in detail and came up with workable solutions. The strong and super-solid UNI.XT extension may look like numerous other standard extensions at first glance, yet it is replete with innovations which make it a far superior product.

The latest version comes with a completely new adjustment ring, which offers a unique feature: based on the tried-and-tested SDM adjustment ring, the RDM version now for the first time ensures that the aluminum tube does not come into contact with the mast anymore, which avoids any contact corrosion. No other RDM extension can offer that. In order to guarantee the same durability despite the reduced diameter, a double-walled sandwich construction of 7075 aluminum outer tube and ovalized T8 inner tube is used (patent pending).

Light is right but only if it doesn't go to costs of durability. Durability as part of the DUOTONE quality has always been one of the defining characteristics of our products - and it stays that way.
STORAGE SLOT
AVOIDS TANGLED ROPES. All UNI.XT and POWER.XT 2.0 feature a slotted top cap. This way you can get rid of the excess rope during storage and transportation.
iSNAP 2.0
Based on the original SDM adjustment ring the iSNAP 2.0 offers some unique benefits: 1. The extension tube cannot come in contact with the mast anymore thus preventing any contact corrosion.
2 THREAD SYSTEM
NOW COMPATIBLE WITH ALL SAIL BRANDS. The UNI.XT features a stainless-steel open pulley enabling loop-loop-go rigging – the fastest and most comfortable way to rig your sail.
DOUBLE FOOT TRIM
30% POWER SAVING. In terms of rigging comfort the UNI.XT offers much more than existing standard extensions.
RAPID RELEASE
INSTANT DE-RIGGING. Due to the modified position of the standard cleat, just place one foot on the extension and pull the rope with a short jerk out of the cleat – done.
