Master Lock 1525 Dial Combination Padlock
The Master Lock 1525 combination padlock is an institutional locker padlock designed for schools, colleges, leisure facilities and workplaces. It combines a fixed three-number combination with a hardened steel shackle, anti-shim protection and optional supervisory key control.
Users can open the padlock without carrying a key, while authorised staff can manage access through the compatible control-key system. This makes the Master Lock 1525 particularly suitable for managed locker installations where administrators may need to open locks or recover forgotten combinations.
Master Lock 1525 Key Features
- Fixed three-number dial combination
- Approximately 1,500 available combination sequences
- 48 mm reinforced stainless steel body
- 7 mm diameter hardened steel shackle
- 19 mm vertical shackle clearance
- 21 mm horizontal shackle clearance
- BlockGuard anti-shim technology
- Automatic dial scrambling when the shackle is closed
- Supervisory key-control facility
- Designed primarily for indoor locker applications
Fixed Three-Number Combination
The Master Lock 1525 operates using a fixed three-number combination. The user enters the assigned sequence using the front dial and then lifts the shackle to open the lock.
The combination is factory assigned and is not intended to be reset by the individual user. This makes the 1525 different from a resettable combination padlock and allows combinations to be recorded and managed as part of an organised locker-control system.
Supervisory Key Control
A compatible supervisory or control key allows authorised personnel to open the padlock without using the assigned combination. This can help schools, leisure centres and workplace managers deal with forgotten combinations, inspect lockers or reallocate storage.
Control keys are normally managed separately and should only be issued to authorised staff. Confirm control-key compatibility and availability when ordering padlocks for an existing installation.
BlockGuard Anti-Shim Protection
BlockGuard technology is designed to help resist shimming attacks around the shackle. Combined with the hardened steel shackle and reinforced lock body, it provides a practical level of security for personal belongings stored in managed indoor lockers.
The Master Lock 1525 is intended for general locker security. It should not be treated as a high-security padlock for valuable equipment, perimeter gates or exposed outdoor locations.
Suitable Locker Applications
| Environment | Typical use |
|---|---|
| Schools and colleges | Student lockers and managed personal storage |
| Universities | Changing-room, departmental and accommodation lockers |
| Leisure centres | Indoor changing-room lockers |
| Gyms | Member and staff lockers in dry indoor areas |
| Workplaces | Staff lockers, uniform storage and personal-effects lockers |
Check Locker Compatibility
Before ordering, check that the locker hasp or staple can accommodate the 7 mm shackle diameter. The available shackle clearance is 19 mm vertically and 21 mm horizontally.
The lock is suitable for many standard locker hasp fittings, but dimensions should always be checked where the locker has a recessed, covered or unusually shaped locking point.
Indoor Use and Care
The Master Lock 1525 is principally designed for indoor lockers. It is not promoted as a weatherproof or marine-grade padlock and should not be used in locations exposed to persistent rain, salt water or severe outdoor conditions.
Keep the dial and shackle free from dirt and periodically inspect the lock for damage or excessive wear. Do not force the dial or shackle if the combination has been entered incorrectly.
Ordering Multiple Padlocks
For schools, gyms and workplace locker installations, record each padlock's combination and locker assignment securely. Confirm whether combination charts, supervisory keys or specific key-control arrangements are required before placing a bulk order.
