Pertanyaan umum tentang MASTER LOCK dari 3G Electric.

What types of Master Lock combination padlocks are available through 3G Electric?

3G Electric stocks Master Lock combination padlocks in standard and long shackle configurations. Models include dial combination padlocks (e.g., MPN 1528D with blue dial, steel body) and scrolling combination padlocks (e.g., MPN 975DCOM with gold dial, brass body). Shackle materials are steel, with body options in brass, stainless steel, or steel. Long shackle models like MPN 175LH and MPN 1500LF provide extended clearance for thicker doors or hasps. Dial colors vary (blue, gold, black) for visual identification. These padlocks are keyless, using a combination mechanism for access.

How does the Master Lock Bluetooth padlock (MPN 4400ECWWG) work?

The Master Lock Bluetooth padlock (MPN 4400ECWWG) uses Bluetooth connectivity to enable keyless access via a smartphone app. It features a black steel body and a boron alloy shackle for enhanced cut resistance. The padlock is part of Master Lock's electronic line, allowing users to grant temporary or permanent access, track usage, and manage multiple locks from a single app. It operates on battery power and is suitable for indoor or sheltered outdoor use. The standard shackle size fits common hasp and locker applications.

What is the key capacity of the Master Lock lockbox (MPN 5440ECWWG)?

The Master Lock lockbox (MPN 5440ECWWG) has a key capacity of 5 keys. It features a digital combination lock with a vinyl-coated metal body in gray. The outside dimensions are 7 1/4 inches in height and 3 1/4 inches in width. This lockbox is designed for securing keys to equipment, vehicles, or facilities, with a weather-resistant finish suitable for outdoor mounting. The digital combination allows keyless access, and the lock can be programmed with a user-set code.

Are Master Lock built-in locker locks like the MPN 1710 keyed to existing systems?

The Master Lock deadbolt lock (MPN 1710) is supplied as keyed random for new installations. If you need it keyed to an existing system, you must specify this when ordering. The lock has a 7/32-inch mounting hole diameter and a 3/8-inch latch bolt projection, making it suitable for standard locker doors. It is a built-in keyed locker lock in silver finish. For retrofitting, ensure compatibility with your locker's mounting hole pattern and door thickness.

What materials are used in Master Lock padlock bodies and shackles?

Master Lock padlocks use a range of materials depending on the model. Bodies are available in brass (e.g., MPN 975DCOM), stainless steel (e.g., MPN 1500LF), or steel (e.g., MPN 1528D). Shackles are typically steel, with some models like the Bluetooth padlock (MPN 4400ECWWG) using boron alloy for increased cut resistance. Brass bodies offer corrosion resistance for outdoor use, while stainless steel provides durability in harsh environments. Steel bodies are common in standard industrial applications.

Can Master Lock combination padlocks be re-keyed or have combinations reset?

Master Lock combination padlocks vary in reset capability. Dial combination padlocks (e.g., MPN 1528D) typically allow user-set combinations that can be changed by following the manufacturer's instructions. Scrolling combination padlocks (e.g., MPN 975DCOM) also permit combination reset. For key-controlled scrolling combination padlocks like the MPN K176CR P569, a control key is used to change the combination. Refer to the product manual for specific reset procedures, as some models may require tools or special steps.
