An ironmongery schedule is the document that separates a considered interior from a finished one.
It lists every item of door and window hardware in a building — every lever handle, every hinge, every turn-and-release set, every pull handle on every pivot door — with model codes, finishes, and quantities. For an architect, it is a specification deliverable. For a homeowner, it is the moment a renovation becomes complete. For a developer, it is the document that determines whether every unit in a project holds its quality claim from the front door to the bathroom.
Most Malaysian ironmongery suppliers can supply a lever handle. Very few can supply a complete schedule from a single design programme — one brand, one aesthetic language, every door category covered.
Kärcher Design can. This is what that schedule looks like.
Lever Handles — The Foundation of Every Schedule
The lever handle is the primary specification in any ironmongery schedule — it appears on every door in the building, is touched more than any other hardware item, and sets the quality register for everything that follows.
In the Studio Series, the lever handle range centres on the ER90 platform — the straight-barrel handle available in all Studio Select configurations and as Studio One. For projects requiring a different profile, the ER90A series offers a slightly tapered variant that reads as softer in residential contexts while maintaining the same material and manufacturing standard.
For a complete schedule, the lever handle specification needs to address:
Standard passage doors — bedrooms, studies, living rooms: full lever set with matching rose, latch, and strike plate. The rose finish should match or intentionally contrast with the lever body — this is where the Studio Select configuration system creates the most visible design decisions.
Privacy doors — master bathrooms, en-suites: lever set with turn-and-release on the inside (thumb turn) and emergency release on the outside. Kärcher Design’s bathroom privacy sets maintain the same external profile as the standard lever — the handle you see from the corridor is identical.
Passage sets without privacy — utility rooms, dressing rooms: lever set with passage latch only, no lock cylinder. Simplest specification; same aesthetic as the rest of the programme.
Bathroom Accessories — Extending the Design Language
The most common gap in a luxury residential ironmongery schedule is the bathroom. Lever handles are specified with precision — and then the towel rail, toilet roll holder, and robe hook are sourced from a different brand, a different finish standard, and a different quality tier. The visual unity of the door hardware is immediately undermined when you look at the walls.
Kärcher Design’s bathroom accessory range — the CEZ series — is produced to the same manufacturing standard as the Studio Series lever handles, in matching finishes. The CEZ1332 series covers:
- Towel rail (single and double bar variants)
- Toilet roll holder (with and without cover)
- Robe hook (single and double)
- Towel ring
- Soap dispenser (wall-mounted)
- Shower shelf
All available in Satin Brass (88), Satin Stainless Steel (71), and Cosmos Black (83) — the same three finishes as the Studio Select lever handles. A bathroom specified entirely in Cosmos Black Studio Series lever handles and CEZ1332 Cosmos Black accessories reads as a single, resolved material decision rather than an assembly of compatible-but-separate products.
For the hardware schedule, note each accessory item separately with its finish code and quantity per bathroom. A standard Malaysian master bathroom will typically require: 1× towel rail, 1× toilet roll holder, 2× robe hooks, 1× towel ring. Multiply by unit count for developer projects.
Window Handles — The Detail Most Schedules Miss
Window handles are specified last and forgotten first. They appear in the ironmongery schedule as a line item, are often sourced from the window supplier rather than the hardware specification, and arrive in a finish that is close to — but not quite — the door handle specification.
Kärcher Design’s window handle range — the EF series — closes this gap. The EF464Q is the primary window espagnolette handle for casement and tilt-and-turn windows, available in the same three Studio Series finishes. It is a clean, architectural form that reads as intentional alongside Studio Series lever handles rather than incidental.
For projects with fixed or sliding windows requiring a different hardware type, the EFG series covers flush pull variants. Both series carry the same surface finishing standard as the lever handle range.
Specification note for Malaysia: Window hardware in Malaysian climates is subject to higher UV exposure and temperature cycling than interior door hardware. For windows with significant solar exposure, Satin Stainless Steel (71) is the recommended finish — it is the most dimensionally stable and surface-resistant of the three finishes under sustained heat and UV load.
Pocket Door Sets — The Hidden Hardware
Pocket doors — doors that slide into a wall cavity rather than swinging — have become increasingly common in Malaysian luxury residential projects, particularly in open-plan living areas where swing clearance is a concern and in bathroom en-suites where a traditional door would interrupt the flow of the space.
Kärcher Design’s pocket door hardware — the EPD and EPDQ series — provides edge pulls and flush pulls designed for pocket door applications. These are recessed into the door edge rather than projecting from the face, maintaining the clean visual plane of a pocket door system while providing the grip and operating mechanism required.
The EPDQ series includes a privacy lock function for bathroom applications — a discreet turn mechanism on the inside face that engages a latch without requiring external hardware. From the corridor, the door face is clean. From the bathroom, the privacy function is fully operational.
Lift-and-Slide Door Sets — For Terrace and Garden Access
Pocket doors — doors that slide into a wall cavity rather than swinging — have become increasingly common in Malaysian luxury residential projects, particularly in open-plan living areas where swing clearance is a concern and in bathroom en-suites where a traditional door would interrupt the flow of the space.

Luxury landed properties in Malaysia — bungalows and semi-Ds in gated communities — frequently specify lift-and-slide door systems for living room to terrace or garden transitions. These large-format sliding door systems require a different hardware category entirely: long pull handles, flush locks, and operating mechanisms rated for the weight and movement of full-height glass panels.
Kärcher Design’s EHSSET28 lift-and-slide set provides the complete hardware package for these applications — handle, lock cylinder, and operating mechanism — in a single specification with matching finish options. For a project where the interior door hardware is specified in Studio Series Cosmos Black, the EHSSET28 in Cosmos Black (83) carries the design language through to the terrace without interruption.
Pull Handles — For Pivot Doors and Statement Entrances
The entrance door of a luxury Malaysian bungalow is the first hardware the visitor touches — and increasingly, the entrance door is a pivot door rather than a hinged door, requiring a long pull handle rather than a lever set.
Kärcher Design’s ES46Q pull handle series provides straight-bar pull handles in lengths from 300mm to 1200mm, in Satin Brass, Satin Stainless Steel, and Cosmos Black. For a pivot door in a GnG bungalow, a 600mm or 900mm ES46Q pull handle in Cosmos Black with a Satin Brass mounting bracket creates exactly the entrance statement that the interior hardware programme promises — without requiring a separate brand or a compromised finish match.
Glass Door Hardware — For Internal Glass Partition Systems
Open-plan interiors frequently incorporate internal glass partitions — frameless glass walls with integrated door systems for study enclosures, wine rooms, and home cinema spaces. These require a different hardware category: glass door patch fittings, floor springs, and handles designed for frameless glass applications.
Kärcher Design’s EGS360Q glass door system combined with the ER46Q glass door lever provides a complete hardware specification for internal glass door applications. Both are available in Cosmos Black and Satin Stainless Steel — the two finishes most appropriate for the contemporary interior contexts where glass partition systems typically appear.
Building Your Schedule — Practical Notes for Architects
A complete ironmongery schedule for a Malaysian luxury bungalow will typically cover eight to twelve hardware categories. When building the schedule from Kärcher Design:
Use the model code system consistently. Every Studio Series item has a model code — ER90B1 0S 83 identifies the handle model (ER90B1), the rose type (0S), and the finish (83 = Cosmos Black). Include the full model code in every line of the schedule. This eliminates finish ambiguity at the ordering stage and ensures the installation team receives exactly what was specified.
Specify finish by code, not by name alone. “Gold” and “Satin Brass” are different things. “Satin Brass” and “88” are the same thing. Use the numeric finish code (88/71/83) alongside the finish name in every schedule line.
Request documentation early. BS EN 1303 certification, ISO 9001 certificates, and product data sheets are available from KeysonAI’s trade team. Request these at specification stage — not at project completion when the contractor is asking for compliance documentation.
Allow for lead time. Studio Select by you configurations are assembled to order. Allow adequate lead time in your project programme — contact KeysonAI’s trade team at specification stage for current lead time information.
