The 110 mm stopper for the Marker Jester is a replacement ski brake for Marker's alpine freeride bindings, not a bottle accessory. The brake is the part that stops a released ski sliding away down the mountain, and a bent or missing one takes the binding out of service.

• A ski brake, not a bottle stopper: stopper is Marker's own term for the brake arms on the binding heel.
• 110 mm width: the brake must be at least as wide as the ski waist, so 110 mm suits skis up to around 110 mm underfoot.
• Fits the Marker Royal Family: the same brake range covers the Jester, Griffon, Duke, Baron, Tour and Squire chassis.
• Supplied as a pair: left and right, so one purchase covers both skis.
• Fitting by a dealer: brakes are part of the release system, so the binding should be function tested after a change.
