Plug Lockout for Standard Connectors

The Hubbell HLDMP is a yellow polypropylene lockout device that encloses standard plugs and connectors up to 5/8 inch cord diameter. It accepts up to two padlocks with a maximum shackle diameter of 5/16 inch. The unit operates from -20 to 140 degrees Fahrenheit and is rated for 15/20 A circuits. Overall dimensions are 4.22 inches long, 3.14 inches wide and 2.57 inches high.

Compatibility Checks Before Ordering

Verify that the cord diameter of the plug you intend to lock out does not exceed 5/8 inch. Confirm that any padlock you plan to use has a shackle no thicker than 5/16 inch so it fits the lockout holes. Ensure the circuit amperage and voltage match the 15/20 A rating marked on the device. Check that the operating temperature range suits the environment where the lockout will be applied.

Suited for Basic Electrical Lockout Needs

This lockout suits maintenance teams and electricians who need a simple, visible way to isolate standard 15/20 A plugs during service work. It is not designed for plugs with cords larger than 5/8 inch or for applications requiring more than two padlocks. Buyers needing lockout devices for specialised connectors, higher amperage circuits or different temperature extremes should look at other products.

Questions about this item

What comes in the box and do I need to buy padlocks separately?

The package contains the yellow polypropylene plug lockout only. Padlocks are not included and must be purchased separately to complete the lockout.

Should I choose a different version for 15 A or 20 A circuits?

This single model is rated for both 15 A and 20 A circuits, so no separate version is required.

How does the 5/16 in shackle size affect which padlocks I can use?

The 5/16 in shackle diameter accepts padlocks up to that thickness, and the unit accommodates up to two padlocks at once.
