The shackle is made from hardened steel material that is strong enough to add another protection level.

How To Choose The Best Padlock For Storage Unit?

What Is The Ideal Padlock Size And Material For Your Storage Unit?

The shackle of your padlock should tightly fit your storage unit door’s latch and hasp to create less space. This keeps thieves from breaking this part by putting a pry bar between the shackle and the hasp. If you need exact information, here is it:

A ⅜-inch diameter shackle with a ⅞-inch opening can fit most storage unit hasp size.

For material, the padlock body should be made from hardened stainless steel that is strong enough to resist corrosion. Meanwhile, shackles should be made from boron carbide - the most secure material that can resist cutting better than hardened steel.

Which Types Of Padlock Should You Choose?

This depends on the security level that you want to provide for your storage units.

The keyed padlock can provide you with basic security to protect your storage units in low-crime places or inside a building that has a secure entrance like cameras.

Meanwhile, the combination padlock is the combination of key locks and a series (4 or 5) of pins to keep the shackle inside the body. It requires you to choose the right pins to open the padlock with a key. This solution works well in areas with high crime.

Is A Shrouded Or Exposed Shackle Better?

The body of the shrouded padlock is extended to cover the shackle as much as possible. This is more difficult for thieves to access the shackle with a bolt cutter or a pry bar. It is more secure than the exposed lock, so it is also more expensive than another.

Do You Need Smart Features?

This also depends on your needs. For example, choose a padlock with smart-key technology if you usually lose your separate key. Weatherproofing is an important feature if your padlock is exposed to the weather. The outside of a weatherproof lock can withstand a bit of corrosion. A cheap lock rarely has this feature, so it can rust when exposed to the weather for a long time.

Which Brands Make The Best Padlock For Storage Unit?

Master Lock

Since 1921, the American Master Lock company has produced many famous security products all over the world because of their product strength and quality. Some of their highlight product lines include combination locks, padlocks, and related security products.
