Warner's X-Small brakes are designed primarily for engaged/disengaged holding applications such as seat adjustment on an airplane – though they can provide a low cycle rate stopping action in emergency situations. As they are electrically released, they will remain engaged in the event of a power failure, which makes them suited to applications where the integrity of the holding force is imperative.

The range consists of six standard sizes which range from 22 mm – 33.5 mm diameter (30g – 100g) and offer up to 50 Ncm of static torque. Customized bespoke adaptor flanges are available.
