FAQ
Buyer questions
What is a master key lock system?
A master key system lets one master key open every lock in a set, while each lock also has its own individual keys. Our Jayco and Dollar sets of 25 come with 2 individual keys per lock plus 4 master keys — ideal for schools and hostels managing many lockers.
What is the difference between 7-lever and 10-lever locks?
Lever count relates to security: more levers mean more possible key combinations. Our 7-lever Jayco and Dollar locks support master-keying; the 10-lever Strong locks offer higher security but are keyed individually (no master key).
Are your padlocks made of full brass?
Yes. Every padlock is full-brass construction, following Aligarh's traditional ~60% copper / 40% zinc composition for corrosion resistance and long service life.
Can I order padlocks in bulk for a school?
Yes — we are a manufacturer and wholesaler. Jayco and Dollar locks ship in sets of 25 with master keys; Strong locks are priced per lock. Contact us for institution pricing.
