Tight-Clearance Piano Hinges

The leaves of these hinges almost touch when the door is closed. They are often used in electrical enclosures for a tight seal.

When the door is closed, the distance between the leaves is larger than the pin diameter, creating an offset to accommodate a gasket or trim.

Lockout Hasps

Low-Profile Lockout Hasps with Label

Same as our other low-profile lockout hasps, but with an attached label to record employee name and department.

Choose-a-Color Lockout Hasps with Label

Lockouts come in different colors for easy identification and to help meet OSHA standards. The label is permanently attached to record employee name and department.

Low-Profile Lockout Hasps

With a smaller overall length, these lockout hasps fit in tighter spaces than other lockout hasps yet still hold a similar number of locks.

Nonconductive Lockout Hasps with Tag Holder

Made of plastic, these hasps limit the risk of shock when you’re locking out electrical equipment. They have a holder for a disposable lockout tag to alert others to repairs.

Pry-Resistant Lockout Hasps with Padlock Slot

A fold-over closing design hinders prying, while a slot instead of holes makes it easy to install multiple padlocks.
