Precision Dippings Manufacturing is the very proud UK inventor and manufacturer of Bloccs waterproof cast or dressing protectors for arms and legs. This year the company has been recognised for outstanding results in innovation and won a 2016 Queen’s Award for Enterprise – the UK’s highest accolade for business success. We have also received two manufacturing awards for the design and production of these waterproof plaster cast covers.

Bloccs waterproof plaster cast covers combine our knowhow in making watertight rubber seals used by dry suit manufacturers with our medical market expertise. These reusable rubber cast covers remain watertight when fully submerged in water. Bloccs protectors keep casts and dressings on arms and legs bone dry, making showering, bathing and even swimming possible during recovery.

Operating since 1964 Precision Dippings is ISO9001 certified, with registration to BS EN ISO 9001:2015. The company has high volume manufacturing and packaging facilities. Products are exported worldwide.
