For more aggressive skiing with the GUIDE binding & for heavier built skiers, the Plum Guide Heel Plates relieve the pressure on the two rear heel pins for increased strength & performance. As now fitted to the YAK bindings. These will mount to most GUIDE bindings from around 2011 onwards, if there is a small threaded hole at the front of the heel base plate, this is where these will mount. They are extremely light weight so for maximum protection of the heel piece we would suggest fitting these plates. Sold as a pair complete with mounting screw, & can be fitted & removed in seconds.
