Bond'er noun 1. One who places goods under bond or in a bonded warehouse. 2. (Masonry) A bonding stone or brick; a bondstone. 
In architecture, bonders, also known as bond-stones and binding-stones, are stones which reach a considerable distance into, or entirely through a wall for the purpose of binding it together. Bonders are principally used when the work is faced with ashlar, and are inserted at intervals to tie it more securely to the rough walling or backing.
