How should hardware substitutions be handled after shop drawing approval?

Any substitutions should be treated as a planned change. The size, performance, surface quality, fixings and suitability of the item to be substituted should be checked. The reason for the change should be noted, the hardware schedule and relevant drawings updated and the appropriate authority gained before any fabrication or purchasing is commenced.

How should hardware model numbers be linked to individual millwork units?

Give each piece of hardware its own identifier, e.g., H-01 or D-01. Add the identifier to the hardware schedule and list it on the respective cabinet elevations or sections. Cross-reference the hardware ID with the unit number to facilitate identification of the location of the product by the manufacturer or installer.

Who should verify hardware clearances before fabrication?

The millwork manufacturer or technical drafting team should ensure hardware allowances are correct based on the proposed cabinet build and manufacturers installation data. The design professional should ensure it is correct according to the design intent. The relevant project team should ensure interfaces with other trades are co-ordinated. Responsibilities should be established before approval.

How should concealed hardware be documented when it cannot be shown clearly in elevation?

Use enlarged sections, plan views or detailed drawings to show concealed cabinet hardware. Include mounting positions, fixing points, required clearances, cut-outs and relevant dimensions. Add a unique hardware reference linked to the schedule so manufacturers can identify the correct product and installation details without overcrowding the main elevation.

What should happen when specified hardware is incompatible with the cabinet construction?

Do not proceed with fabrication using an incompatible product. Identify the conflict and assess whether the cabinet construction or hardware selection needs to change. Review the alternative against the design, dimensions, performance and installation requirements. Update the affected drawings and schedule, then obtain approval for the revised solution before production.

Millwork Hardware Schedule: Guide to Shop Drawing Details

A cabinet consists of many parts other than doors, drawers and panels. The hinges, slides, locks and other hardware will dictate how the cabinet operates. If these are unclear in your drawings then it could cause problems when trying to choose the right hardware or fitting it properly.

A millwork hardware schedule will eliminate any confusion. It provides information on what hardware is required, the specific details, how many are required and the cabinet unit it belongs to. This can be used with shop drawings to provide clarity to designers, manufacturers and installers.

This guide covers how to document millwork hardware, link individual fittings to cabinet units, check clearances and manage product changes before manufacturing. It also explains how professional millwork shop drawing services support accurate documentation and help prevent avoidable issues during production and installation.

What Is a Millwork Hardware Schedule?

A millwork hardware schedule is an organised list that details what hardware items are included in a cabinet, joinery item or custom wood item. The schedule will show you what items go where, how many you need of each and their specifications.

It commonly covers:

Cabinets door hinges and access panel hinges.
Standard, deep and specialist drawer slides.
Securing hardware such as locks and latches.
Handles, pulls and knobs.
Fasteners, brackets and mounting accessories.
Concealed hardware, soft close hardware and specialist hardware.

Working in conjunction with shop drawings, hardware schedules are used to indicate the location of the hardware and how it will be fixed to the millwork. This schedule contains the necessary information regarding the product.

The Architectural Woodwork Institute (AWI) also recommends that a hardware schedule is included with your shop drawing submittals. Including information such as manufacture/supplier and model number. This can be a useful document to review.

Why Does Hardware Need to Be Documented in Shop Drawings?

The size of the hardware, where it is fixed in place and its movement will also affect how you build your cabinet. Full extension drawer slides, for example, will require the cabinet to be a certain depth, the drawers to be wide enough and that there is enough space to attach the hardware. If this information has not been considered then this could be an issue for the manufacturer to overcome.

Clear shop drawing hardware documentation helps teams address these decisions before production.

It supports four important project outcomes:

1. Reduced construction conflicts: Sizes and installation requirements for hardware can be compared with the sizes of cabinets, materials and interior layout.

2. Greater accuracy: Correct identification of the right products, quantities and codes becomes possible instead of generic descriptions.

3. Improved coordination: Architects, designers, cabinetmakers and installers have the same information about hardware.

4. More controlled modifications: If any modification occurs, the affected pieces and drawings will be known before the new information gets into production.

The main principle is simple that hardware should be coordinated with the cabinet design, not added after the construction details have been finalised.

What Information Should a Hardware Schedule Include?

A Hardware Schedule should provide everyone involved with an overview of what fittings they will need, where they will go and how they should be installed. It should be detailed enough to ensure that manufacturers/suppliers know exactly what they are looking for.

The following information is often included:

Details to include	Explanation
Hardware code	A unique code to identify each item
Type of hardware	Hinge, drawer slide, lock, handle or fastener
Manufacturer	Name of the company that makes it
Model number	The product’s exact model or reference number
Finish	Required colour or surface finish
Quantity	How many items are needed
Cabinet location	Which cabinet or unit needs the hardware
Fitting details	Where and how the hardware should be installed
Product information	Manufacturer’s product sheet, if required

How Different Hardware Items Are Shown in Shop Drawings

Each type of hardware has different fitting and space requirements. Shop drawings should identify the selected product and show where and how it fits into the cabinet.

1. Hinges

Hinges will be used to open/close cabinet doors. Record details of the manufacturer, model number, the angle they open to and finishes. Include information on where the hinges are situated and how they’re fixed. If using hidden hinges include any mounting information on drawings.

2. Drawer Slides

Drawer slides will influence the overall size of your drawer. Ensure you note down the slide model, length, type of extension and load rating. Ensure there is sufficient depth and side clearance inside the cabinet.

3. Locks and Latches

When secure storage is required in a cabinet include details of the lock including type, model number, finish. Indicate where the lock will be fitted, any cut outs required and extra bracing needed.

4. Fasteners and Fixing Hardware

Screws, brackets and other fasteners hold millwork components together. Document their type, size, material and quantity where specified. Show the fixing positions and clarify which items the millwork manufacturer or other trades must supply.

Clear details for each hardware type help manufacturers select suitable products and fit them correctly during fabrication and installation.

How Should Hardware Schedules Link to Individual Millwork Units?

It can become complicated if the schedule does not indicate where items fit. The best way to do this is to allocate a unique reference to each hardware item and link to the correct cabinet or millwork unit.

For example:

H-01: Concealed soft-close hinge – used on cabinet units C-01, C-02 and C-05.
D-01: Full-extension drawer slide – used on drawer units C-03 and C-04.
L-01: Cam lock – used on storage unit C-06.

These will be referenced in the hardware schedule and noted on the shop drawings.

For larger projects, having a unit schedule will help identify which cabinet goes where, what size it is, and what type. This can then be matched to the unit numbers in your hardware schedule.

This is especially useful on hospitality and commercial and multi-unit residential projects where cabinets may look the same but have different inner layouts or security requirements.

It also means that if you need to make any changes to your drawer slides, you can easily see which units they’re going to go in.

A Practical Checklist Before Approving Shop Drawing Hardware

Before approving a millwork shop drawing package for manufacturing, check that all hardware details are complete and correctly coordinated.

Each hardware item has a unique reference code.
Manufacturer names and model numbers are clearly listed.
Hardware codes match the correct cabinet units.
Quantities match the number of doors, drawers and fittings.
Hinges suit the door size, weight and opening angle.
Drawer slides have sufficient space and clearance.
Lock positions and required cut-outs are clearly shown.
Fasteners and fixing methods are documented.
Concealed hardware has supporting section details.
Product specifications are available for reference.
Unconfirmed hardware and proposed substitutions are identified.
All drawings reflect the latest approved hardware details.

A final review involving designers, manufacturers and installers helps identify missing information and resolve potential fitting issues before fabrication begins.

What Hardware Specifications Should Be Included?

A millwork hardware specification should include the manufacturer, model number, hardware type, dimensions, material and finish. It should also state the load capacity of hinges and drawer slides, opening angles, extension type and any movement requirements. Include fixing details such as screw sizes, mounting positions, installation methods and required clearances. The schedule should also record the quantity needed for each cabinet or millwork unit and reference relevant manufacturer datasheets or installation instructions. These details help manufacturers identify compatible products and fit them correctly during fabrication and installation.
