Tha mòr-ionad àiteachais sreath BAA na shiostam giùlain mòr-ionad làn-aonaichte, air a ghreimeachadh agus air a seuladh airson beatha an aonaid. Tha fàinne a-muigh le flange aig na h-aonadan mòr-ionad seo a tha air a ro-drileadh agus air a thapadh gus diosc a ghabhail a-steach. Tha siaft stub snàthaichte air an fhàinne a-staigh stèidhichte airson a chuir suas gu furasta air cha mhòr gàirdean inneil sam bith.
