How to select the correct door handle, lock or spring
The OEM or component reference is usually the most reliable starting point. If this is not available, identify the exact machine manufacturer, model and, where relevant, production version before comparing physical dimensions.
A practical selection order is:
- OEM or component reference – compare the original part number or cross-reference where available.
- Exact machine and model – machine brand alone does not confirm compatibility.
- Version or production period – different revisions of the same model family can use different door components.
- Component type – determine whether you need a complete handle, latch, locking mechanism, spring, locking kit or another part of the door system.
- Orientation – check left-hand, right-hand or reversible configuration where specified.
- Mechanical interface – verify mounting centres, hole spacing, door thickness, hook geometry and other relevant dimensions.
- Electrical specification – electromechanical locking components must also match the stated voltage and connection requirements.
- Complete assembly or individual component – check exactly which parts are included.
- Origin – distinguish OEM/original parts from compatible non-original replacements.
Do not select a door component from overall dimensions or appearance alone. A handle, latch, lock and spring can belong to the same door system while using completely different mounting and operating interfaces.
Door handles for professional ovens and equipment
Complete door handles can be specific to a machine family and even to a particular production version. The Fagor 12161224 OEM oven door handle is listed for specified Fagor AE, APE, AG and APG oven models, including production-version information.
This is why selecting by machine brand alone is not sufficient. Start with the OEM reference or exact model and then confirm the version and handle configuration. For other components used on this equipment, browse our Fagor spare parts.
Door latches and locking mechanisms
A door latch is not the same component as a complete handle. Some machines use a separate latch, strike or central locking mechanism that works together with the handle assembly.
The Rahrbach 5403060 door handle latch, for example, uses a 43 mm centre-to-centre hole spacing. This mounting dimension is part of the mechanical interface and must be checked together with the component reference and machine application.
Other locking components can be left-hand, right-hand or reversible. Always verify the specified orientation before ordering; a similar-looking mechanism with the opposite handing is not automatically interchangeable.
Electromechanical door locks
Some professional equipment uses electrically operated locking mechanisms rather than a purely mechanical latch. These components require both the mechanical interface and electrical specification to match.
For example, the UNOX KCR1035A electromechanical lock is a 12 V DC locking unit for specified UNOX oven models. Voltage is therefore an additional technical specification for this component, but it does not replace model and OEM-reference verification.

Door springs and return mechanisms
Door springs can perform different functions depending on the machine. They may be part of a door return, counterbalance or handle and locking mechanism. The correct spring should therefore be selected by its function and machine application, not simply by its length or diameter.
The Winterhalter OEM 60003697 door spring measures Ø15 × 170 mm and is listed for specific Winterhalter dishwasher models and versions. Another spring with the same approximate dimensions should not automatically be treated as equivalent.
Depending on the spring, relevant specifications can include:
- spring function;
- outside diameter;
- overall length;
- specified load or tension;
- mounting interface;
- machine and model application.
Left-hand, right-hand and reversible door parts
Orientation is a separate compatibility specification. Door handles and locking mechanisms can be designed for left-hand or right-hand installation, while some components are specifically designed to be reversible.
Do not infer orientation from general shape or dimensions. Check the product specification for LH, RH or reversible and compare this with the original door configuration.
Mounting dimensions and door configuration
Relevant dimensions depend on the type of component. For handles and latches these can include mounting-centre distance, hole spacing, overall dimensions, hook length or supported door thickness. For springs, diameter, length and specified load may be more important.
Dimensions therefore need to be interpreted as part of the complete mechanical interface. A matching centre distance or overall length alone does not confirm fit.
Complete assemblies and individual components
Check whether the product is a complete door-handle or locking assembly or only one component of the system. Depending on the machine, the handle, latch, spring, hinge or locking mechanism can be supplied separately.
An individual latch or spring should not be interpreted as a complete handle repair kit unless the product specification explicitly states that the required components are included.
Machine brand and component manufacturer
The brand of the machine and the manufacturer of the door component are not always the same. Specialist component manufacturers can supply handles, latches and locking mechanisms that are used across machines from several equipment brands.
Where this information is available, use the machine manufacturer and model to confirm the application and the actual component manufacturer and reference to identify the door hardware itself.
OEM and compatible door components
Brooks Parts supplies both OEM/original components and compatible non-original replacements. These terms describe the origin of the replacement component, not simply the machine brand it fits.
An OEM/original component is supplied under the stated original manufacturer reference. A product marked Compatible (non-original) is an alternative replacement for the stated machine or reference and should not be interpreted as a component manufactured by that machine brand.
For both types, the OEM or component reference, exact machine application, orientation and mechanical or electrical specifications remain the leading selection criteria.
Before ordering a door handle, lock or spring
Identify the existing component reference whenever possible and confirm the exact machine and version. Then compare component type → orientation → mounting interface → dimensions → electrical specification where applicable → complete or individual part → OEM or compatible.
