2 sizes of tabs

1" (large) triangle

• works well on large buttons with a small shank.
  

  
  small 5/8" tab
  

• If the button is too small for the white clip, use a thin wire to attach.

small tab

• This size is useful for buttons with thick, chunky SHANKS.
  
  large 1" tab
• Use the large pad when the button has a thick, bulky shank, such as Bakelite or Celluloid. Use wire to mount these buttons.
• A small-SHANK button works well with a clip on 1" triangle. The button should be larger than 1" to cover the triangle (so the tab will not show from the front.)
• The pad is flexible to some extent, but if the shank is too thick/chunky, you may want to enlarge the hole a hole punch.
