This stainless steel variant features an 81mm case size with a 57mm backset, combining contemporary styling with extended reach for substantial door installations. The stainless steel forend finish offers superior corrosion resistance and a modern, professional appearance that complements brushed or polished chrome door furniture. With a 57mm centre measurement, this larger configuration is well-suited to heavy-duty timber doors in commercial environments or high-specification residential properties. The 57mm backset provides the depth required for doors with deeper rebates or where enhanced security positioning is needed. The Union SwitchLatch technology enables quick, tool-free radius latch reversal, reducing installation time significantly, whilst the anti-rattle adjustable strike allows for precise on-site fine tuning. Comprehensive security features include a chamfered bolt design that improves side load performance and resists drilling attacks, anti-pick protection, and hardened steel pins that prevent sawing. The 14mm deadbolt delivers secure positive deadlocking with key operation from either side.
