Frequently Asked Questions
- What is a passage function knobset?
A passage function knobset provides free knob operation from both sides without any locking capability. Both the interior and exterior knobs always operate freely to retract the latch, making it ideal for hallways, closets, and other doors that require access without privacy or security locking. - What is the difference between passage and entrance functions?
Passage function provides free knob operation from both sides with no locking capability (no cylinder or keys). Entrance function provides keyed locking from the exterior and free knob operation from the interior, requiring a key to unlock from outside. Passage knobsets have no cylinder assembly. - What is Through Pin (TP) mounting?
Through Pin (TP) mounting uses a pin that passes through the door and knob assembly to secure the knobset. This provides a secure and reliable mounting method suitable for knobset applications while allowing straightforward installation and future servicing if required. - Can this passage knobset be converted to entrance or privacy function?
No. The passage knobset is designed specifically for non-locking applications and does not include the cylinder assembly or privacy button mechanisms required for entrance or privacy functions. For locking applications, you would need to purchase the appropriate entrance or privacy knobset. - What is the adjustable backset and why does it matter?
The backset is the distance from the door edge to the centre of the knob. This knobset has an adjustable 60-70mm backset, allowing it to suit different door preparations. Always measure your door preparation before installation to ensure correct backset adjustment. - Is this suitable for both left and right-hand doors?
Yes. The Symmetry Bell TP passage knobset is reversible and suitable for both left-hand and right-hand door applications, providing installation flexibility without requiring separate handed versions.
Additional Information
- Symmetry Range Integration:
This passage knobset is part of the comprehensive Symmetry door furniture range. The Bell knob profile provides traditional styling suitable for residential interiors while coordinating with the broader Symmetry knobset family including entrance and privacy functions for consistent aesthetic appearance across different door types. - Passage Function Operation:
The passage function provides free knob operation from both sides at all times with no locking capability. This is ideal for doors requiring access without privacy or security locking such as hallways, walk-in wardrobes, closets, and utility rooms. The latch retracts when either knob is turned from any side. - Satin Stainless Steel Finish:
The satin stainless steel finish provides contemporary brushed appearance with durability suitable for residential applications. This finish coordinates with modern interior hardware and appliances while offering resistance to corrosion and tarnishing. The 5 year finish guarantee covers tarnishing, discoloration, or corrosion when properly maintained. - Through Pin Mounting System:
The Through Pin (TP) mounting system provides secure installation appropriate for passage knobset applications. The pin passes through the door and knob assembly to hold the hardware firmly in place while allowing straightforward installation and future maintenance if required. - Tubular Latch Mechanism:
The 60-70mm adjustable tubular latch provides 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. The adjustable backset accommodates different door preparations without requiring additional components. - Australian Standards Compliance:
All Symmetry products are tested in accordance with Australian Standards for quality, security, and durability, ensuring reliable performance in Australian residential applications and compliance with local building requirements even for non-locking passage function applications. - OneCyl® System Compatibility:
While passage knobsets do not include cylinder assemblies, they are part of the OneCyl® compatible Symmetry range, allowing coordinated hardware styling across properties that include both passage function and entrance function doors with consistent Bell knob profile aesthetics. - Door Thickness Range:
Suitable for door thickness from 30mm to 51mm, covering a broad range of residential door constructions. Note that the minimum door thickness is 30mm for knobsets, which is thinner than the 35mm minimum for many leversets, providing flexibility for various door applications. - 5 Year Finish Guarantee:
The satin stainless steel finish is covered by the 5 year finish guarantee. Lockwood guarantees to replace Symmetry products if within five years from the proven date of purchase they tarnish, discolour, or corrode when properly installed and subject to no more than fair wear and tear. - Coordinated Door Furniture Systems:
For properties with multiple doors requiring different functions, this passage knobset coordinates with Symmetry Bell entrance knobsets (keyed exterior doors) and privacy knobsets (bathrooms, bedrooms with turn button) to provide consistent Bell knob profile and satin stainless steel finish throughout the property.
