Swivel height adjustable lumber support
A height adjustable lumbar support provides three easily adjusted operator positions for

move with the operator. The lumber support is tightened with two adjustable double pull
forward straps.
The lumber support height can be adjusted with one hand whilst being
worn.
Waist belt
The waist belt features a quick release buckle mechanism that sits against the
