Plum KAIRN 12 RENTAL STOPPER 100 MM Ski Bindings

Plum KAIRN 12 RENTAL STOPPER 100 MM: a ski touring binding designed for both ascents and descents

The Plum KAIRN 12 RENTAL STOPPER 100 MM is a ski touring binding designed to accompany your outings with a clear balance between comfort on the ascent and performance on the descent. It is intended for those seeking a PIN TECH insert binding with an integrated ski stop, a DIN release range of 4 to 10, and settings adapted to the demands of ski touring. Its design features a lightweight construction, a boot entry compatible with low-tech insert soles, and precise control over pressure on the ski. With the Plum KAIRN 12 RENTAL STOPPER 100 MM, the tension between ascent and descent is resolved through a technical interface that is easy to use and specifically designed for ski touring.

Front toe piece: precise engagement and low-tech insert-compatible boot entry

The front binding of this model features a PIN TECH system compatible with all soles equipped with low-tech inserts, ensuring direct engagement with boots designed for this type of setup. The 20 mm length adjustment allows the interface to be tailored to the ski and boot within the specified parameters. This design of the front stopper ensures a boot engagement consistent with touring use, while maintaining a mechanism suited to repeated transitions between ascent and descent.

The 100 mm ski stop width integrated into this model meets the specified configuration for the binding and completes the assembly without adding unnecessary complexity.

Heel piece: power transmission and ski flex

The heel piece contributes to power transmission during the descent thanks to the integrated elasticity system, designed to offer better ski flex. This feature has a practical benefit for you: it supports the ski’s movement without artificially stiffening the assembly when pressure is applied. In the context of a touring ski binding, the heel piece does more than just hold the boot in place; it contributes to the binding’s overall performance as you transition from ascent to descent.

The weight of 355 g per binding is part of this pursuit of efficiency in motion, with a construction designed to remain consistent with touring use.

Climbing wedges: three heights to manage the ascent

The climbing wedges offered on the Plum Kairn Stopper allow you to adjust your climbing position according to the terrain profile. The three available heights are 0, 50, and 65 mm, offering several working positions for the ascent depending on the route’s requirements. This arrangement of the wedges helps structure the effort during a tour, while keeping the binding’s settings intuitive.

For a climbing/descending-oriented approach, this range of positions allows you to use the binding in a technical setting without deviating from the manufacturer’s specifications.

Safety and release: DIN 4–10 and reliability of adjustment

Safety here relies on a release range of DIN 4 to 10, with a setting designed to ensure the binding’s behavior stays within the specified limits. This DIN setting is a key safety feature in ski touring, as it identifies the intended release level of the product. The binding also includes a ski stop, a component that enhances equipment management during ski touring.

• DIN 4–10: You have a defined release range to control the binding’s operation.
• Integrated ski brakes: You benefit from braking capabilities built into the product’s design.
• 20 mm length adjustment: You can adjust the binding within the limits specified by the manufacturer.
• Compatible with low-tech inserts: You can use the binding with boots designed for this setup.

Materials and durability: technical construction and French manufacturing

The construction of the Plum KAIRN 12 RENTAL STOPPER 100 MM combines 7075 aluminum, steel, and POM plastic. This combination results in a ski touring-oriented binding design, with components selected for their role within the mechanical system. The product is manufactured in France and comes with a 5-year warranty—two key points that highlight the brand’s commitment to this model.

The availability of ski-stop widths in 80, 90, 100, and 110 mm further demonstrates that this model is part of a family of configurations designed to accommodate various ski widths, while maintaining the technical integrity of the line.

If you’re looking for a ski touring binding built around a true balance between ascent, release, and descent, the Plum KAIRN 12 RENTAL STOPPER 100 MM combines the essential features for a technical and intuitive experience. It provides a clear foundation for choosing a structured touring binding with integrated ski brakes, climbing wedges, and a defined DIN range.
