Lewis Woolf Grip-tight Ltd owned a rubber plantation in the Far East. At the British Industries Fair its products were listed as patent pneumatic and non-pneumatic baby soothers, rubber teats, bottles, and flycatchers. They had various premises in Bournbrook: rear of 507 Bristol Road; Old School in Hubert Road for rubber processing; Offices 144 Oakfield Road; 508 Bristol Road shop used for storage; 519 Bristol Road as a canteen. They also used the former TASCOS building on the corner of Alton Road until it was destroyed in a massive fire. A dentists surgery now occupies the site.
