Elesa now has stainless steel versions of the CQ lock with 90 deg opening and IP65 protection. They are suitable for corrosive environments such as food equipment or wet locker rooms where lower grade materials may have a limited life. The CQ Inox locks come in two types, each with two closing lever possibilities to suit different door/frame depths. AISI304 stainless is used throughout for strength and corrosion resistance – this coupled with an SBR rubber retaining washer makes the CQ Inox range suitable for many harsh environments. For ease of access, key patterns on the CQ locks are available as two-wing and triangular types using polyamide technopolymer keys for convenience and security
