Frequently Asked Questions
- What is an entrance function knobset?
An entrance knobset provides keyed access from the exterior side and free knob operation from the interior side. The exterior knob is locked and requires a key to operate, while the interior knob always provides free exit without requiring a key for emergency egress. - What is the difference between cylindrical and tubular latch mechanisms?
Cylindrical latches integrate the latch mechanism within the knob assembly itself and typically have a fixed backset. Tubular latches are separate latch bodies installed in the door edge with adjustable backsets. This Imperial knobset uses a 60mm cylindrical latch mechanism. - How does the concealed snap-on trim work?
The vertical mounting screws are installed first to secure the knobset, then snap-on trim pieces are fitted over the mounting points to conceal the fixing screws, providing a clean finished appearance with no visible fixings on the door face. - Can this be used on fire-rated doors?
Yes. Lockwood Symmetry furniture has been successfully fire tested up to 2 hours on fire door assemblies in accordance with Australian Standard AS 1905.1-1997. Fire performance depends on the complete doorset configuration and Fire Resistance Level rating. - What is the difference between the two finish options?
Polished Stainless Steel (PSS) provides a bright reflective mirror-like finish. Satin Stainless Steel (SSS) provides a contemporary brushed finish with reduced reflection. Both finishes are covered by the 5 year finish guarantee. - How does the OneCyl® system work with this knobset?
OneCyl® is Lockwood's exclusive cylinder assembly solution that allows cylinder interchangeability across the entire Symmetry range. This means you can replace or upgrade cylinders without replacing the entire knobset, enabling flexible keying arrangements and master key systems.
Additional Information
- Symmetry Range Integration:
This entrance knobset is part of the comprehensive Symmetry door furniture range. The Imperial TP knob profile provides traditional styling suitable for residential interiors while coordinating with the broader Symmetry knobset family including passage, privacy, and dummy functions for consistent aesthetic appearance. - Entrance Function Operation:
The entrance function provides keyed locking from the exterior and free knob operation from the interior at all times. This ensures emergency egress capability while maintaining security control at the entry point. The latch bolt retracts when either the key is turned from outside or the knob is operated from inside. - Cylindrical Latch Mechanism:
The 60mm cylindrical latch integrates the latch mechanism within the knob assembly, providing 13mm throw for positive door engagement. The D-strike includes an anti-rattle tab as standard, reducing noise and movement when the door is closed. - Vertical Mounting with Concealed Fixing:
The vertical mounting screw system provides secure installation with snap-on trim that conceals all fixing points, creating a clean finished appearance. This mounting method is appropriate for entrance applications and simplifies installation on standard door preparations. - Fire Rating Compliance:
Successfully fire tested up to 2 hours on fire door assemblies in accordance with Australian Standard AS 1905.1-1997, Part 1: Fire Resistant Doorsets. Fire performance is system-based and depends on the complete doorset configuration including door construction, frame, and all hardware components. - Australian Standards Compliance:
All Symmetry products are tested in accordance with Australian Standards for security and durability, ensuring reliable performance in Australian residential applications and compliance with local building requirements. - Cylinder and Keying Systems:
The LW4 5 pin Lockwood C4 brass cylinder assembly is compatible with 6 pin systems and allows rekeying without cylinder replacement. Standard supply is keyed to differ with two keys per lock. Restricted special keying arrangements are available for projects requiring keyed alike or master keyed systems. - OneCyl® Cylinder Interchangeability:
The OneCyl® system allows cylinder assembly replacement across the Symmetry range without replacing entire knobsets. This enables upgrading from standard keying to restricted keying, changing keying arrangements, or replacing worn cylinders while retaining existing door furniture and hardware. - Stainless Steel Construction:
Knob constructed from stainless steel and brass with steel chassis and stainless steel bolt head, providing durable construction suitable for residential entrance applications. Available in polished or satin finish options to suit different aesthetic preferences. - Door Thickness Compatibility:
Suitable for timber doors with thickness ranging from 32mm to 46mm, covering standard residential door applications. Ensure door thickness falls within this range before ordering to guarantee proper installation and operation. - Coordinated Door Furniture Systems:
For properties with multiple doors requiring different functions, this entrance knobset coordinates with Symmetry Imperial TP passage sets (hallways, non-locking doors), privacy sets (bathrooms, bedrooms), and dummy knobs (inactive door panels) to provide consistent knob profile and finish throughout the property.
