What is a Padlock Protector?
A padlock protector, also known as a padlock shield or lock shield, is a metal device that surrounds the padlock to prevent it from being cut, smashed or tampered with. It is usually made of thick, hardened steel or titanium to withstand attacks. The protector has openings on the side or bottom to allow the padlock shackle to pass through and lock as usual.
Once installed, a padlock protector acts as an extra layer of defense. Even if the padlock itself is compromised, the attacker would then have to spend more time and effort to penetrate through the tough metal protector. This increases the noise, visibility and difficulty of breaking in, deterring criminals.
Why Should You Use a Padlock Protector?
Here are some key reasons why installing a padlock protector is recommended for security:
Prevent Bolt Cutters
Bolt cutters are commonly used by thieves to snip through padlock shackles. A padlock protector blocks access to the shackle, preventing bolt cutters from fitting around it. The protector also shields the shackle making it impossible to cut.
Withstand Sledgehammers
A sledgehammer can easily smash an unprotected padlock. Padlock protectors are made of hardened steel or titanium that can withstand hammer blows. The protector absorbs and deflects the impact without damage.
Impede Lock Picking
The small keyway openings on most padlock protectors prevent lock picking tools from accessing the padlock. The protector blocks the keyway, leaving no room for picks to manipulate the lock components.
Deter Drilling
Drilling the padlock cylinder is another break-in method. The padlock protector is engineered with concave shaping to deflect drill bits attempting to reach the cylinder. Drilling the protector itself is very arduous and time-consuming.
Increase Time
Forcing any type of entry through a padlock protector requires extra time and work. This delays the criminal, increases their risk of being noticed, and may compel them to abandon their attack and move on.
Types of Padlock Protectors
There are a few different types of padlock protectors available. The main types include:
Open-Shackle Padlock Protectors
Designed for open-shackle padlocks. The protector encloses the padlock body while allowing the open shackle to pass through openings on the sides.
Closed-Shackle Padlock Protectors
Made for closed-shackle padlocks. The shackle passes through a hole on the bottom of the protector while enclosing the padlock body.
Hasp Protectors
Cover hasp staples and mounting hardware to prevent hacking, pinching, sawing, prying or bending attacks on the hasp.
Disk Padlock Protectors
Made for round, discus or puck style padlocks. The protector fits around the circumference of the circular padlock body.
| Type | Description |
|---|---|
| Open-Shackle | Encloses padlock body, open sides for shackle |
| Closed-Shackle | Hole in bottom for shackle, encloses body |
| Hasp Protector | Covers hasp staple and hardware |
| Disk | Made for round, puck style padlocks |
Materials Used
Most padlock protectors are made from thick, durable metals. Common materials include:
Hardened Steel
Steel that has been treated with heat and/or chemicals to increase strength and resistance to cutting or drilling. Provides the highest level of protection.
Stainless Steel
Resists corrosion and rust while still offering substantial duress resistance. Stainless steel provides good durability at a lower cost than hardened steel.
Aluminum
Very lightweight and affordable option for low-moderate security needs. Not as strong against tools as steel but serves as a deterrent.
Titanium
Extremely hard and durable metal that offers the strength of steel at half the weight. High cost limits titanium to high-end protectors.
Protectors by Security Level
Padlock protectors provide varying degrees of protection based on their design and material used. Typical security levels are:
Low Security Protectors
- Thin aluminum or mild steel construction
- Minimal duress resistance
- Low cost, lightweight option
Medium Security Protectors
- Hardened steel or thick stainless steel
- Withstand hand tools and moderate attacks
- Suitable for chains, gates, storage units etc.
High Security Protectors
- Thick, hardened steel or titanium
- Withstand prolonged power tool, hammer and pry attacks
- Ideal for high-risk applications
