Is the Master Lock 1525 right for your school?

Choose the 1525 when students need a combination padlock and authorized staff need supervisory key access. The key-control feature is the central difference from the Master Lock 1502; confirm the key arrangement and any required keys as part of the quote.

Check locker fit before ordering

Master Lock specifies a padlock eye at least 5/16 in. in diameter for this model. The standard shackle is 3/4 in. tall, 13/16 in. wide and 9/32 in. in diameter. Measure the space around the actual latch as well as the opening; compare standard, LF and LH shackle options when more clearance is needed.

What should a replacement or bulk request include?

Send the model, quantity, locker application and whether the school has an existing control system. A combination chart supports administration; keep it restricted to authorized staff. Request confirmation of options, availability and delivery timing for your order.
