The Perkins Brailler Straight Extension Keys, One Hand Extension Keys, and Space Bar Extension Key are braille writer accessories designed to make use of the Perkins Brailler (see separate entries) easier for individuals with limited hand strength and dexterity, including those with the use of only one hand. Extension keys attach to any Perkins Brailler and fold up when not in use to allow the brailler to fit into a carrying case. Straight Extension Keys, model 22-0202-6, reduce the effort required to operate the Perkins Brailler by 30 percent. They are intended for two-handed use. One Hand Extension Keys, model 22-0201-6, reduce the required keyboard handspan from seven to four inches, allowing the user to emboss a full braille cell with one stroke of either hand. The Space Bar Extension Key, model 22-0205-9, makes the space bar more accessible to users with limited thumb movement.
