Frequently Asked Questions
- What is the difference between 127mm and adjustable 60-70mm backset models?
The 127mm backset model (7511C series) is a fixed backset configuration for doors requiring this specific measurement. The adjustable 60-70mm model (7511A series) can be adjusted to suit either 60mm or 70mm backset applications, providing more installation flexibility. - What is the OneCyl cylinder system?
OneCyl is Lockwood's exclusive one cylinder assembly solution that provides the convenience of cylinder interchangeability. This allows the cylinder to be easily changed or keyed alike with other Lockwood locks without replacing the entire lockset. - Can this deadlatch be used on fire-rated doors?
Fire rating suitability depends on the complete door system and lockset assembly. Consult the manufacturer's fire rating documentation or contact Lockwood technical support for specific fire door applications. - Is this suitable for exterior doors?
While this deadlatch can be used on entrance doors, it provides latching function only. For exterior door security, it should be used in conjunction with a separate deadbolt or as part of a complete entrance lockset with deadlocking capability. - What makes stainless steel finish suitable for residential applications?
Satin Stainless Steel provides excellent corrosion resistance, durability, and a contemporary appearance that complements modern residential design schemes. The satin finish minimizes fingerprints and maintains its appearance with minimal maintenance.
