Male and Female Color Options

Male models use HBLMR part numbers. Meanwhile, female models use HBLFR part numbers.

First, choose the male or female style needed for your panel. Next, select black, white, green, red, blue, brown, orange, yellow, or gray.

For example, HBLMRR is a red male model. By contrast, HBLFRR is the red female model. However, current stock may vary by color and part number.

Check the Connection Style

Double set screw models connect the cable with two screws at the rear contact. By contrast, stud and bus-bar models use different rear connections.

If you need a bus-bar connection, view our Series 16 bus bar receptacles. Also, browse our Series 16 inline cam connectors for cable-mounted plugs.

The mounting and cable connection must match your equipment. Therefore, send us the current part number or a clear photo if you are unsure.

You can also add matching snap-back covers to help cover unused panel connections.
