Helpful Tips
- Round-End Aesthetic: The 5800/5900 Series features round-end (curved end) plates with soft, flowing lines that provide an elegant alternative to traditional square-end plates. The curved profile complements both contemporary and traditional architectural styles, creating a refined appearance that has made these plates a favorite among leading Australian architects for decades.
- Cylinder Hole Function: The 5900 plate includes a cylinder hole that accepts Lockwood cylinders and rim cylinders, enabling keyed access control. This provides security options including keyed entry from exterior, privacy override capability (using turn inside with keyed override outside), exit control (allowing exit without key but requiring key for entry), and comprehensive access control for commercial applications.
- Cylinder Selection: The cylinder hole is compatible with Lockwood cylinders and rim cylinders. Cylinders are ordered separately and must be matched to your mortice lock series and keying requirements. Common cylinder types include keyed cylinders (standard key operation), restricted cylinders (high security with patent protection), thumb-turn cylinders (interior turn with exterior key), and blank cylinders (decorative cover when cylinder not required).
- Configuration Flexibility: The 5900 plate with cylinder hole can be paired with various interior hardware configurations including levers (for passage or locking functions), knobs (traditional or contemporary styles), turns (privacy or indicator turns), or plain plates (exterior keyed operation only). Select configuration based on your specific access control and operational requirements.
- Series Compatibility - 5800/5900: The 5900 Series is designed specifically for use with Lockwood 3780/3580 Series mortice latches. This is distinct from the 5600/5700 Series which suits 3770 Selector and 3570 Synergy locks. Ensure correct series selection - using 5900 plates with 3780/3580 locks ensures proper alignment of cylinder hole, fixing centres, and operational components.
- Finish Selection Guide: Three premium finishes available: Aged Brass (AG) - warm, aged appearance with character patina ideal for traditional and heritage applications; Chrome Plate (CP) - bright, highly reflective finish for contemporary and modern designs; Satin Chrome (SC) - brushed, low-maintenance satin finish suitable for high-traffic commercial environments. Consider maintenance requirements, architectural coordination, and environmental conditions when selecting finish.
- Application Examples: Ideal applications include commercial building entry doors (keyed access control), office doors (privacy with override), hotel/motel room doors (keyed entry, interior privacy), institutional doors (controlled access), retail security doors (staff access control), and high-end residential entry doors (keyed entry with quality aesthetic).
- Architectural Heritage: The Lockwood brass door furniture range represents the culmination of decades of experience in the design and manufacture of high-quality door furniture. Over the years, the Lockwood brass door range has evolved to become the product of choice for leading Australian architects in commercial, institutional, and industrial applications, with proven performance in the most demanding environments across Australia.
- Fire Rating Considerations: Fire rating of up to 4 hours applies when the plate is installed with a fire-rated Lockwood mortice lock on compliant fire door assemblies in accordance with AS1905.1:2005. Fire performance is dependent on the complete doorset type and configuration. Compliance is system-based and limited by the FRL (Fire Resistance Level) of the complete doorset assembly. Consult fire door specifications and ensure all components including cylinder meet required standards.
- Durability and Testing: Lockwood brass plates undergo rigorous durability testing to Level D8 under Australian Standard AS4145.2-2008, representing 500,000 operational cycles. This extensive testing ensures long-term performance in high-traffic commercial and institutional environments, providing confidence in the product's ability to withstand decades of demanding use while maintaining operational integrity and aesthetic appearance.
- Pairing with Interior Plates: This exterior plate with cylinder hole is typically paired with interior plates that provide the operating hardware (lever, knob, or turn). Common pairings include: exterior cylinder + lever with interior lever (passage or privacy function), exterior cylinder + plain with interior turn (privacy with keyed override), exterior cylinder + lever with interior plain (keyed entry, free exit). Consider the complete lockset assembly when specifying - ensure interior plate function matches operational requirements.
- Australian Design and Customization: All Lockwood brass door furniture is designed, assembled, and customised in Australia to suit the specific requirements and environmental conditions of the Australian market. This local design expertise ensures optimal performance in Australian climates, compliance with Australian building standards and accessibility requirements, and availability of support and spare parts through local networks.
- Cylinder and Accessories Ordering: Cylinders, cylinder guards, cylinder screws, and related accessories are ordered separately from the plate. When ordering, specify: cylinder type (keyed, thumb-turn, restricted), finish to match plate, keying requirements (keyed alike, keyed different, master keyed), and cylinder length appropriate for door thickness. Consult cylinder selection guide or technical support for correct cylinder specification.
- Non-Returnable Item: This is a made-to-order item that is non-returnable and cannot be cancelled once ordered unless it is faulty or damaged. Please carefully verify all specifications including finish selection, series compatibility with your mortice lock (3780/3580 Series required), cylinder requirements, configuration options, and suitability for your specific application before placing your order. If uncertain, consult the complete Lockwood Plate Door Handles Catalogue or contact technical support for specification assistance.
