Features
Tri-Circle 40mm Laminated Steel Padlock
The Tri-Circle 40mm laminated steel padlock is a compact keyed padlock intended for lockers, cabinets and other everyday security applications.
Its layered steel body provides a practical balance between durability, size and cost. The padlock is particularly suitable where a conventional keyed lock is preferred to a combination padlock or an integrated locker lock.
Benefits of a Laminated Steel Padlock
A laminated padlock body is formed from multiple steel plates assembled into a compact lock body. This established construction is commonly used for general-purpose padlocks where straightforward keyed access and a robust metal body are required.
- Compact format for compatible locker hasps and cabinet fittings
- Layered steel body suited to regular everyday use
- Key-operated access without remembering a combination
- Suitable for individually assigned lockers and storage points
- Can be removed and replaced without changing the locker lock
- Useful as a spare or replacement padlock for compatible hasps
- Suitable for personal, workplace and general storage applications
- Simple operation with no batteries or electronic programming
Where Can the Tri-Circle Padlock Be Used?
| Application | Suitability guidance |
|---|---|
| Workplace lockers | Suitable for compatible padlock hasps where individual users are responsible for their own locker key. |
| School and college lockers | Can be used on lockers fitted with an appropriate hasp, subject to the site's key-management and lost-key procedures. |
| Staff storage cabinets | Suitable where the cabinet fitting provides adequate clearance for the padlock body and shackle. |
| Toolboxes and equipment cases | Appropriate for compatible light-duty storage fittings where a removable keyed padlock is required. |
| Cupboards and storage cages | May be used where the staple, eye or hasp is correctly aligned and suitable for the padlock. |
| General indoor storage | Suitable for routine security applications that do not require a certified high-security or specialist weather-resistant padlock. |
General-Purpose Padlock Security
This Tri-Circle model is intended for everyday general security rather than high-risk, insurance-rated or controlled-access applications. The security of the complete installation also depends on the strength of the locker hasp, cabinet fitting, gate eye or other attachment point.
| Requirement | Guidance |
|---|---|
| Everyday locker security | A practical choice for personal belongings stored in a compatible locker in a normally managed environment. |
| High-value contents | Consider a higher-security padlock and confirm any insurance requirements before storing valuable equipment or property. |
| Exposed outdoor use | Select a padlock specifically rated for prolonged outdoor exposure where the lock will be subject to rain, salt, dirt or severe weather. |
| Emergency or shared access | A managed master-key, keyed-alike or combination-lock system may be more appropriate where several authorised people require access. |
| Restricted or regulated storage | Check the applicable security standard rather than relying on a general-purpose padlock. |
Check Padlock and Hasp Compatibility
A padlock should be selected to fit the locking point rather than by body size alone. Check the locker hasp, cabinet eye or staple before ordering. Exact padlock measurements are provided in the Specification tab.
- Confirm that the shackle will pass through the hasp or locking eye
- Check that there is enough clearance around the padlock body
- Make sure the hasp and staple align without forcing the shackle
- Check that the closed padlock will not obstruct the locker handle
- Confirm that nearby doors or fittings will not strike the padlock
- Inspect the hasp for excessive wear, distortion or corrosion
- Replace damaged locker hasps before fitting a new padlock

Choosing the Correct Type of Padlock
| Padlock type | Best suited to | Main consideration |
|---|---|---|
| Standard keyed padlock | Individually assigned lockers, cabinets and general storage. | Users must retain their keys and the site needs a lost-key procedure. |
| Keyed-alike padlocks | Multiple storage points that need to be operated by one authorised key. | Loss of the operating key may affect every padlock in the group. |
| Master-keyed padlocks | Managed installations requiring individual user keys and supervisory access. | The key plan and replacement-key control must be securely managed. |
| Combination padlocks | Sites wishing to avoid issuing and replacing mechanical keys. | Forgotten codes and abandoned lockers still require a management procedure. |
| Weather-resistant padlocks | Outdoor or exposed locations subject to regular moisture and dirt. | Confirm the manufacturer's environmental rating and maintenance requirements. |
| Long-shackle padlocks | Recessed, widely spaced or difficult-to-reach locking points. | Additional shackle clearance may also increase exposure to attack. |
