One of the trademarks of the Harrisville Designs looms is the high castles. The tool trays take advantage of this design and create a convenient storage space where it is needed most. Extra shuttles, bobbins, and reed hooks can be stored in front of and directly above the weaving area. The shallow depth of the trays prevent tools from being out of sight. Made from the same hardwood as the looms, the tool trays become a practical and attractive addition. They come completely assembled and in various sizes to fit the different looms made by Harrisville Designs.
