The Action Zero cavity frame is a premium system available in 80kg or 180kg manufactured by Joey Cavity frames to suit our Square set cavity trims. This system incorporates a 4-wheel trolley design with a dual precision bearing for quiet, smooth operation. The innovative Joey Zero bracket minimises the gap between the track and the door. This is ideal for floor to ceiling cavity sliding doors as it provides a sleek, clean finish eliminating the need for cover strips. All exposed timbers are 19mm KDHW. The Action Zero can also be made to suit custom sizes and finishes.
