The handle tray was designed to fit on top of the trigger handle in your bucket. 3 sides of the tray are slanted so you can pick or drag small nuts, washers and other items easily with your rubber gloves. The tray comes with velcro on the bottom so It can be easily removed and placed on another truck. Small drain holes have also been included to reduce puddling during rain conditions.
