What is an SB lock?

The answer is that an SB (single bit) lock is a cam lock available in five different lengths that is used in many different applications. I’m going to expand on that definition to give you a clear idea of ​​just how versatile the SB lock really is.

The name SB stands for “single bitted”. This is where the cuts in the key are only on one side of the key. They are very similar to a standard house key, only smaller. They are available in five different sizes from 3/8 “to 1-1 / 2” long. Many manufacturers make this type of lock with the standard 54G keyway. Some manufacturers call this a utility lock. They are typically used to secure cabinets, desks, tool boxes, utility cabinets, and even paper towel dispensers found in bathrooms. These locks are considered low security.

SB Lock Features:

• Economical utility lock on standard 54G keyway

• Constructed of die-cast zinc

• The face of the lock can be zinc or a stainless steel cover in chrome or black

• Available in five lengths

• You can have the same password, different password, or master password

If these locks are purchased from an authorized service center, they can be entered in batches of one to thousands. They are used in applications where the idea is to keep honest people out. These locks are easily bypassed and should not be used when greater security is required.

SB locks internally use wafers instead of locking pins. These wafers are made of brass and are designed from 0 to 7 which will correspond to the cuts on the key. For instance; if 1-3-5-3 wafers are used, the key is also cut into 1-3-5-3. When the two match, the lock will work.

SB locks from different manufacturers can be mixed and used together as long as they are all in the 54G keyway. Keys from one manufacturer must operate locks from another manufacturer. As a basic type lock, in many cases price is the deciding factor as to where to buy these locks. Many are made in China, where these types of locks have been made for years. The limiting factor for buying in China is quantity. Tens of thousands of SB locks must be ordered at one time. Most of the manufacturers that use this type of padlocks buy them in authorized service centers where they can get them in any quantity and assemble them to measure.
