The carrier board is robustly manufactured. The board is equipped with a full-surface Velcro fastener. The Velcro fastener is secure and stable and ensures that the rubbers do not slip. The rubbers can be changed or replaced in a few simple steps. To do this, simply remove the old covering and place the new covering on the Velcro fastener. The offset handle makes it easier to work in corners and gaps. The handle is ergonomically shaped and ensures a comfortable grip. The hook and loop fastener can be easily cleaned with a wire brush. To do this, simply pull the wire brush over the hook and loop fastener. This cleans the hook and loop fastener and the coverings hold better again.
