Product Description

The Master Lock 410 Series Zenex lockout/tagout padlock has a nonconductive thermoplastic body that functions in temperatures from -70 to 350 degrees F; retains its key until locked to ensure it is not left unlocked; and has a keyed different 6-pin tumbler cylinder for security (over 40,000 key codes). "Property of" labels with blank lines for customization and "Danger: Locked Out Do Not Remove" labels in English, French, and Spanish are included. This padlock is part of a lockout/tagout (LOTO) safety procedure required at facilities where a device or energy source needs to be isolated during maintenance and repair. When used according to manufacturer's recommendations, this product is covered by a limited lifetime warranty against defects in workmanship or materials.

The lock body is Zenex, a UV-stabilized thermoplastic with tensile strength and resistance to corrosion. The shackle is plated to resist corrosion, but non-hardened, as some LOTO procedures require the shackle to be cut with bolt cutters. The lock mechanism is lubricated with a National Sanitation Foundation (NSF) certified lubricant that meets category code H1, designating this lock safe for use in food processing areas.

Specifications

*Overall dimensions 1-3/4 x 1-1/2 x 3/4 inches (44 x 38 x 19.05 mm) (H x W x D)
Weight 3.36 oz.
Vertical shackle clearance 1-1/2" (3.8 cm)
Horizontal shackle clearance 25/32"
Shackle diameter 1/4" (6 mm)
Shackle pull force withstood 800 lb.

*H is height, the vertical distance from the lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.

Vertical shackle clearance is the distance from the top of the lock body to the farthest point on the inside of the shackle. Horizontal shackle clearance measures the space between the shackle heel and shackle toe. Shackle pull force is tested to American Standard for Testing and Materials (ASTM) F883.

Lockout/tagout (LOTO) safety procedures require that lockout devices meet Occupational Safety and Health Administration (OSHA) 1910.147(c)(5) standards for quality assurance. Safety padlocks, also called lockout padlocks, use colors or warning labels to help prevent machine operation or power activation during maintenance and repair. The security level of a safety padlock is measured more by the number of key codes (also called key changes or key cuts) it can offer than by its ability to withstand physical abuse. A padlock with more pin tumblers and higher precision key cylinders has more key codes available, making it harder to pick, and less likely for a large facility to inadvertently give two employees padlocks with the same key code. Keyed alike locks allow one user to open many padlocks with one key. Keyed different means each lock is opened by its own key. Master keyed locks can be opened if the original key is lost or unavailable during an emergency.

Master Lock manufactures padlocks, combination locks, and related security products. The company, founded in 1921, is headquartered in Milwaukee, WI.

This is a great lock for lockout/tagout purposes.

Mine came with one key. Keep in mind that some locksmiths may refuse to duplicate a lockout key, and for good reason. It is a safety device. Having 2 keys presents the opportunity for another person to inadvertently remove the padlock while it is being serviced downstream. If the equipment is energized, it could kill you.

The lock body is plastic. This lock is designed to provide reasonable resistance to accidental/unauthorized energizing of a switch or disconnect.

This lock is NOT designed to provide resistance to forced access. This lock could easily be opened with a hammer, but keeping in mind the intended use of this device, that is not an unreasonable amount of security.

If you are buying this lock, keep in mind it's intended function -- reasonable resistance to accidental/unauthorized use or engagement of a switch or disconnect while service is being performed downstream of the circuit. It is not designed to be a long term use lock.

A buddy of mine uses these on his gym locker because it is lightweight and unique allowing it to be identified easily. The key cannot be removed from the lock while it is unlocked, which helps prevent a misplaced key as well as ensuring that the lock is fully engaged before you walk away.

This is clearly not intended as a high-security lock for valuables, but as a safety lockout, it seems very good. The key cylinder contains 6 pins, and I believe 5 of them are spool-shaped security pins. Additionally, the shape of the key forces anyone picking the lock to work at an awkward angle. This is a very difficult lock to pick -- more difficult than many heavy-duty models from Master Lock. As such, it makes a great practice lock for anyone who enjoys lock picking as a hobby. I bought it for that purpose, and I have not been able to pick it yet. Highly recommended, either for its intended use as a safety lockout or as a challenging practice lock!

Be very careful when picking this lock open! It's a key-retaining lock but if you pick it open you won't have the key in it which allows you to turn the cylinder past the point it's supposed to turn. If you do this, the pins will fall out of the cylinder and into the inside of the lock body. This makes the lock rattle and the pins may jam up the mechanism and prevent the lock from ever opening again.

No stickers included. Not that I want to have to deal with returning the lock to get a new one in hopes IT will have stickers included. Would be nice to be able request stickers be sent seperately.

This nice-looking safety lock has two wide flat panels (one on each side) that made it easy to customize the security message with my own lock-out safety message on my own stickers.

Just bought 4 more of these for work, because some of our guys like to lose them. I've never had these break before, and we put them through some serious abuse. We've got lots of limestone and talc powder too, and it doesn't bother these at all. The longer lock helps them to stay out of the way and the bright color is nice and obvious. Love it!

Despite being plastic, these feel very solid. The locks come with a set of labels in English, Spanish, and French (and you apply whichever set you'd like). I also like the variety of colors they come in, which makes it easier to pick out your lock amongst a bunch of others.

Funny story- someone in my apartment building was using my washer in the public area of the basement. Obviously this ran my energy bill up and got in the way of me doing my laundry. Solution- same thing we did at a factory I worked at. Lock it out!

I was really happy to see that they made the 110-120V lockouts at a reasonable price as I am used to using the bigger industrial lockouts. This lock was a perfect civil solution to an uncivil problem.
