A complete custom safety padlock order defines the model and shackle, quantity, key-opening relationships, physical key copies, color allocation, identification artwork and packing requirements. Approve those details together before bulk production so the delivered locks can be issued without reorganizing the order on site.
Customization is useful when it makes a lock easier to assign, identify and replace. A logo alone does not establish who controls the lock or which key opens it. For procurement teams, the most valuable outcome is a repeatable specification that connects the physical product to the site’s lock register.
Start with application fit and model selection
Choose the model before preparing artwork. For the PROLOCKEY P series, the supplied drawings cover 25 mm, 38 mm and 76 mm clear shackle heights, each with steel and nylon versions. Confirm shackle diameter, inside width and body clearance against the intended lockout device.
Use our shackle material and length guide to compare these dimensions. A successful artwork approval does not resolve an incorrect mechanical fit.
If the order includes several models, place each model and configuration on a separate line. Avoid a single total quantity followed by a long sentence listing several colors and lengths; that format makes allocation errors easier to miss.
Define keying before adding identification
Specify KD, KA groups or an approved master-key arrangement in writing. For KA, identify the number of independent groups and locks in each group. For a master-key hierarchy, define which groups the master can open and who will control it.
The number of supplied physical keys is a separate field. A second key copy is additional access to the same lock or group, not a new keying system. Record how spare keys will be delivered and managed.
When extending an existing system, provide the earlier order reference and key-group identification through the supplier’s agreed channel. Ask for compatibility confirmation before adding locks. Our KD, KA and master-key comparison explains the order structures.
Build a color plan your site can explain
Colors can distinguish departments, crews or other categories defined by the site. Write down the meaning of each color and keep the same meaning in the order sheet, lock register and training materials.
Do not assume there is a universal rule that red always means electrical or blue always means piping. In U.S. general industry, OSHA 29 CFR 1910.147(c)(5)(ii)(B) addresses standardization within the facility; it does not prescribe that department color map.
Ask for the available stock color references or an agreed custom-color sample. A screen image is useful for discussing a color but is not a reliable physical color standard. Obtain approval of the actual sample when color matching matters.
Keep lock identification separate from key identification
Plan the fields around what the user needs to recognize quickly. A physical lock might carry a company logo, unique lock ID and employee or department reference. A key may carry a group or key reference for controlled inventory management.
Example structure:
| Field | Example | Purpose |
|---|---|---|
| Physical lock ID | LK-0101 | Identify one physical item |
| Assigned employee ID | E-026 | Connect the item to its assigned user |
| KA group reference | G-026 | Identify the specified shared-key set |
| Department color | Site-defined blue | Support the site’s visual system |
These identifiers are illustrative. They are not an actual customer order or a PROLOCKEY key code. Keep a controlled register linking the fields rather than expecting color or a logo to carry all the information.
Prepare an artwork file and a variable-data list
For fixed artwork, send the logo, required wording, language and placement preference. For variable markings, supply one row per physical lock, with the exact ID or name that should appear. A spreadsheet is easier to validate than photographs of handwritten numbering lists.
Ask the supplier to show the proposed location and readable text size. Confirm which markings will be on the body, which on the label, and which on the key. Marking methods and available space depend on the selected product.
Proofread the approval copy for spelling, warning text and numbering. Pay particular attention to characters that are easy to confuse, such as O/0 and I/1. Establish whether a replacement lock should keep the old identifier or receive a new one.
Use a quotation specification that can become an issue list
The following is an illustrative format; quantities and identifiers are examples, not an offered product bundle.
| Order field | Example specification |
|---|---|
| Product | P38S, steel shackle; dimensions per approved drawing |
| Total quantity | 120 locks |
| Key arrangement | 30 independent KA groups, four locks per group |
| Operating keys | One physical operating key per KA group; confirm acceptance with site policy |
| Master key | None |
| Color allocation | 60 red, 60 blue; exact group allocation in attached spreadsheet |
| Identification | Unique lock ID on each body; group reference on the operating key |
| Artwork | Approved logo and label file, revision A |
| Packing | Separate and identify each group; match packing list to the allocation sheet |
| Destination and timing | Delivery country, required date and agreed shipping terms |
The allocation sheet should reconcile to the total quantity. If a group spans several colors, state that explicitly rather than leaving the supplier to infer it.
Approve a representative sample before bulk release
Check the sample’s mechanical fit, key-opening relationship, key copies, marking, color and packing identification. Review the proposed variable-data list alongside the sample; one correctly engraved sample does not establish that every serial number in the order is correct.
Keep the approved specification and artwork revision with the purchase order. For a reorder, reference that approved version and list the changes. Confirm current availability, lead time and documentation for the particular order instead of assuming they are identical for every customized model.
Frequently asked questions
Can locks in one order have different names or numbers?
PROLOCKEY offers identification options for review. Send the full variable-data list and artwork so feasibility, placement and order requirements can be confirmed.
Does a custom logo change the key system?
No. Artwork and keying are separate specifications. Both should be approved in the order sheet.
What information speeds up a quotation?
A selected model, quantity by configuration, key-group plan, color allocation, identification file and delivery destination give the supplier a clear starting point.
