Walking Grate Height Adjustment
Depending on the tread depth and design of the boot or as the horizontal brushes wear you may need to
adjust the height of the walking grate to expose more or less of the bristle for proper cleaning of the
boots. The grate is set at the factory with approximately 3/8” of the horizontal brush bristles above the
walking grate. Follow the steps below and refer to the photos to adjust the height of the walking grate.
• Caution – system is not designed for individuals over 300 lbs. in weight.
• Do not totally remove the black threaded spacer or use it alone for a height adjustment.
• The black threaded spacer must be on the nut shown below for proper grate support.
• The height adjustment can only be adjusted for 3/8”, ½”, or 5/8” bristle height.
• Modification of the system beyond manufacturer’s specifications could result in personal
injury, system malfunction, and will void warranty.
