Padlock GERDA KMKN S40 brass shackle padlock, symmetric key, model 0KMBPP04000.9813DB

GERDA KMKN S40 brass shackle padlock with a symmetric double-sided key is designed for everyday residential and light commercial use. The padlock provides basic mechanical protection for gates, lockers, cabinets and storage units. Its brass shackle and body construction aim to resist corrosion in standard outdoor and indoor environments, while the symmetric key profile allows convenient operation from either side of the key.

Advantages

The KMKN S40 combines a compact, durable brass body with a hardened brass shackle to offer corrosion resistance and consistent mechanical performance. The symmetric double-sided key simplifies locking and unlocking, particularly in low-light or awkward access conditions. Its simple mechanism is easy to maintain and suitable for frequent, routine use where moderate security is sufficient.

Suitable for

• Home gates and garden sheds
• Lockers, cabinets and storage boxes
• Light commercial doors and storage units
• Temporary or portable security applications

When it may not be suitable

This padlock is intended for basic to moderate protection and is not designed for high-security applications where resistance to advanced picking, drilling or cutting is required. For environments with extreme weather, heavy vandalism risk or where insurance mandates high-security hardware, a specialised high-security or weatherproof lock should be considered.

Key specifications

• Body material: brass
• Shackle material: brass
• Key type: symmetric (double-sided) key
• Use case: residential and light commercial
• Typical mounting: through hasp, staple or latch compatible

How to use

Insert the symmetric key into the cylinder and turn to retract or engage the locking mechanism. Position the shackle through the hasp or staple and push it into the body until it locks audibly. To unlock, insert the key and turn in the opposite direction, then pull the shackle free. Regularly clean the keyway and apply a small amount of graphite or silicone-based lubricant to the cylinder to maintain smooth operation; avoid oil-based lubricants that attract dirt.

What to consider before purchase

• Required level of security: suitable for basic/moderate protection only
• Shackle clearance and diameter to match hasp or staple dimensions
• Environmental exposure: brass offers corrosion resistance but is not fully weatherproof
• Key management: symmetric double-sided key is convenient but may be less secure than specialised key systems

Usage recommendations

For reliable daily performance, fit the GERDA KMKN S40 with a compatible hasp or staple that matches the shackle clearance, avoid leaving the lock submerged or exposed to highly corrosive chemicals, and perform periodic lubrication of the cylinder to extend service life.
